Educational Objectives

» Differentiate the options available to utilize an angled screw channel hybrid abutment

» Recognize the armamentarium needed for you and your lab to deliver an angled screw channel restoration

» Understand why angled screw channels are relative to you and your practice

Abstract

Clinicians today want to eliminate possible dental implant restorative complications and fabricate restorations with longevity and reparability built into the design. Ideally, all dental implant restorations would have the ability to be retrievable without compromising the integrity of the prosthetic. Traditionally, a screw-retained restoration required more accurate implant positioning and offered several advantages over a cemented restoration. Benefits included known retention, ease of removal or retightening, and assurance of no lingering cement.

The inability to angle all implants ideally for screw retention arises with the relationship of teeth to the relationship of bone or the lack of quality or quantity of bone. In some cases, the available bone to establish initial primary stability is located in areas that will not allow the long axis angulation of the implant to be in an ideal position to allow a screw-retained restoration. The need has existed for a screw-retained prosthetic solution when the long axis of the implant does not coincide with the lingual or occlusal aspect of the final restoration.

CASE PRESENTATION: Implant Guided Surgical Guide and Immediate Provisionalization

Categories:

Author(s):

Date: 08-13-2020 09:26:40 am

    Guided surgical guides and premade provision­als are now considered a routine procedure because of their accuracy and predictability. This case details file merging of cone beam computed tomography (CBCT) DICOM data with iTero Element (Align Technology) STL file data to create a virtual plan­ning platform, design and 3D print the surgical guide, and place implants. 

Patient Presentation
The 21-year-old patient sustained facial, bone, and dental injuries (Figure 1) in an automobile accident while jogging, including the loss of teeth Nos. 7 and 8 (Figure 2). After discussing alternatives, benefits, and complications, the patient agreed to implant placement and immediate provisionalization of the missing anterior teeth.

Virtual Planning
We file-merged surface morphology STL data from an iTero Element digital scan (Figure 3) with the DICOM data of a NewTom VGi CBCT scan taken by Mobile Im­aging Solutions. Using SIMPLANT v16 software (Dentsply Sirona Implants), we created a virtual wax-up for optimal shape and contour of the missing teeth (Figure 4).

After crown down planning, we determined each implant location to allow precise placement of the lingual access cylinder for the retention screw of the screw-retained implant restoration, as well as to ensure it was optimally located in available bone (Figure 5). Us­ing 3Shape software, Glidewell Labs CAD designed and milled full-body polyetheretherketone (PEEK) provision­als with engaging titanium inserts (Figure 6). The tita­nium inserts, created to allow for screw retention, were secured with luting cement. Using the planning data, we designed a surgical guide that was 3D-printed using a Stratasys Objet 30 3D printer with FDA-approved MED 610 polymer (Figure 7).

Treatment
After administration of local anesthesia (4% Septo­caine, Septodont), we inspected the tooth-supported guided surgical guide and trial-fitted in the patient’s mouth. Designed inspection windows were viewed to ensure proper adaptation (Figure 8). As flapless surgery was planned, we used a tissue-removal drill followed by a sequential series of osteotomy drills (Figure 9). Care was taken to take each drill to full depth, with the drill shoulder contacting the metal guide insert (Figure 10).
We placed Glidewell 3.7 mm x 13 mm and 4.7 mm x 13 mm implants and torqued them to 35 Ncm with the surgical guide in place (Figure 11). We placed the flat of the fixture hex parallel to the flat of the surgical guide with the implant at full depth. PEEK provisionals were placed (Figure 12). No occlusal adjustment was neces­sary. We removed the composite restoration on tooth No. 9 and used Spectrum TPH3 (Dentsply Sirona Restor­ative) to develop an improved esthetic result (Figure 13).

Accuracy Leads to Success
Accurate scan data produces accurate file merg­ing, which leads to extremely accurate design and 3D printing of guided surgical guides. Accurate guided surgical guides then allow for such precise placement of implants that premade provisionals can be placed at the same time as the implants. With a 100% digital workflow, clinicians can produce predictably accurate premade provisionals in the anterior esthetic zone.

CASE PRESENTATION: Overdenture Implant Placement Using a 3D-Printed Surgical Guide

Date: 07-15-2020 08:58:55 am



A healthy, 70-year-old woman presented with a loose mandibular complete denture, complaining that she was unable to chew hard and crunchy foods. She requested minimally invasive narrow diameter implants to stabilize her denture. Her mandible edentulous ridge had
adequate bone volume to allow for flapless implant placement (Figures 1 and 2).

A radiopaque PVS (Green-Mousse, Parkell) was applied to the intaglio of the mandibular complete denture, and the patient and denture were CBCT scanned using the PreXion3D Eclipse (PreXion). Cotton rolls were used to aid in occlusal and soft- tissue separation.

Using Blue Sky Plan (Blue Sky Bio) dental implant planning software, I opened the DICOM files to be- gin digitally planning the patient’s treatment. Her treatment included four 2.9 mm x 12 mm LOCA-  TOR Overdenture Implants (Zest Dental Solutions) (Figure 3). A surgical guide incorporating these im- plants was designed and exported into a 3D print- able file. I printed the guide design file on Dental   SG biocompatible surgical guide material using the Form 2 3D printer, both from Formlabs (Figure 4).

The osteotomy was prepared through the 3D printed surgical guide using the drill stop as an indicator. After the guide was removed, the remaining osteotomies were prepared freehand. Four implants were placed using a minimally inva- sive technique, and fully inserted using a torque wrench (Figures 5–8). The LOCATOR abutments were placed onto each implant and torqued to 30 Ncm (Figure 9). The patient’s bone density was ideal, which resulted in a high insertion torque (Figure 10). Recesses in the denture were prepared using acrylic burs from the Denture Prep & Polish Kit (Zest Dental Solutions) (Figure 11).

Because the patient preferred not to immediately attach the implants, CHAIRISIDE Soft Reline Material (Zest Dental Solutions) was injected into the intaglio of the denture and placed onto the edentulous ridge. After complete polymerization, the denture was removed, trimmed, and inserted back onto the ridge (Figure 12). The patient returned 3 months after treatment to receive final prosthetic procedures.

CASE PRESENTATION: Guided Implant Placement & Restoration in a Narrow Ridge

Categories:

Author(s):

Date: 07-15-2020 08:33:47 am




Today, we’re finding that more and more patients are presenting to the dental practice seeking tooth replacement with dental implant treatment. The need for implant therapy usually results from teeth that are severely decayed, vertically fractured, or periodontally involved.

A patient presented to my practice wanting to replace missing teeth with dental implants in the areas of teeth Nos. 28, 29, and 30 (Figure 1). According to the patient, these teeth were extracted a few years prior without any form of socket preservation, resulting in a deficient edentulous ridge. To accurately assess the area for bone height and width, as well as identify any crucial anatomical landmarks, a CBCT was used. Using the CS 8100 (Carestream Dental) (Figure 2), the narrow ridge was scanned to see if there was adequate bone.

When the CBCT scan was achieved, a treatment plan (Figure 3) was created using 3DDX (3D Diagnostix) where the edentulous ridge would be restored with 3 dental implants in addition to the placement of grafting material. A blend of cortical mineralized and demineralized bone-grafting material would be used in any residual areas around the dental implants.

When the treatment plan was presented to the patient and accepted, the fabrication of a tooth-borne pilot drill surgical guide was initiated and completed using 3DDX within a short amount of time. The surgical guide was tried in to confirm it was completely seated onto the supporting teeth, and to ensure there was no movement upon any pressure.

With a simplified drilling protocol using a guided surgical kit (OCO Biomedical) (Figure 4), the osteotomies were prepared using the AEU7000 Surgical Motor (Aseptico) and handpiece with copious amounts of sterile irrigation. Once the osteotomies were complete, an implant driver was used to place 3 Engage (OCO Biomedical) dental implants (Figure 5) precisely into the ridge until increased torque was necessary. The ratchet wrench was then connected to the adapter and the implants torqued to final depths, reaching a torque level of about 40 to 50 Ncm.

Any residual areas around the implants were grafted with a cortical mineralized and demineralized bone-grafting material (Goldendent) to optimize the area (Figure 6).

Upon examination 4 months later, the soft tissue and bone surrounding the dental implants were very healthy (Figures 7 and 8), so the implants’ Implant Stability Quotient values were tested with an Osstell unit. Since the dental implants had a high reading—indicating osseointegration—impression posts were inserted (Figure 9) and a full-arch im­pression was taken using a vinylpolysiloxane light/tray material (Panasil, Kettenbach) (Figure 10). From these impressions, final abutment and Zenostar (Ivo­clar Vivadent) crown restorations were fabricated.

After delivery from the dental lab (Arrowhead Dental Lab), the definitive abutment and crown restorations were tried in and radiographs taken to ensure complete seating. Once confirmed, the abutments were torqued into place (Figure 11) and the splinted crown restorations were seated with Premier Implant Cement (Premier) (Figure 12).

With proper planning, placement, and restoration, a dental provider may predictably restore a patient’s smile to proper form and function. In today’s practice, it is essential to have the appropriate skills, technology, and dental materials to accurately deliver implant treatment in a systematic, effective approach.

Date: 05-18-2020 06:36:11 am

The accuracy of implant placement has increased dramatically with the advent of guided surgical guides. The digital workflow offers the possibility of premade provisionals that can be delivered at the time of implant placement. Considering that precise data is the key to excellent outcomes, CBCT-based DICOM data can be file-merged with STL intraoral scan data to create a virtual planning platform. Planning software allows crown-down planning, with virtual representation of missing teeth and virtual placement of implants. This case will present the workflow used to plan and precisely place 3 implants to support an immediate placed 4-unit anterior provisional bridge. Following a bicycle accident in which he collided with a truck, this 28-year-old patient lost his 4 maxillary incisors. The patient presented with no contraindications to implant placement. After a discussion of alternatives, benefits, and complications, the patient consented to have 3 implants and a premade provisional placed.

Virtual Planning

Using implant planning software, CBCT-based DICOM data (PreXion) was file-merged with STL scan data (iTero Element scanner, Align Technology) to create a virtual planning platform. The 4 missing incisors were virtually created and placed in an optimal position to allow screw retention with the access hole lingual to the incisal edge. The implant locations were planned in relation both to available bone and the position of the wax-up maxillary incisors. As there was insufficient room for implant placement of tooth No. 10, three implants were planned with a cantilever 4-unit bridge resting on the implants. The access cylinders for the retention screws were precisely designed to be lingual to the incisal edges.

Using the planned bridge design, Glidewell Labs milled a PMMA Implant Provisional and cemented 3 titanium insert cylinders using Shofu luting cement. The planned surgical guide was created using an Objet30 3D printer (Stratysis) with FDA-approved MED610 translucent polymer.

Treatment

After administering 4% Septocaine (Septodont) local anesthesia, an anterior ridge incision with bilateral vertical releasing incisions was performed to allow observation of the implant to titanium insert fit for the premade provisional bridge. Using the 3D-printed surgical guide, sequential osteotomy drills implants were placed to shoulder stop depth. To ensure precision fit of the premade provisional, the Glidewell Direct Inclusive Tapered implants were placed with surgical guide in place and torqued to 35 Ncm. Close inspection of the PMMA provisional to the implant surface revealed a precise fit. No adjustment of implant depth or occlusal adjustment was necessary.

Outcome Summary

The patient was extremely happy with the immediate esthetic result, and the healing after 6 months was excellent. Superior outcomes can result from the use of accurate scan data for file merge and virtual planning. In this case, precise accuracy was achieved using a guided surgical guide sufficient to place 3 implants and immediately seat a premade provisional with no adjustment necessary.

Author(s): ,

Date: 05-10-2020 08:17:28 am

Prosthetically driven digital implant planning is revolutionizing implant dentistry, resulting in improved surgical and prosthetic outcomes. Likewise, utilizing a full digital workflow with in-house 3D printing and milling improves the efficiency of implant cases, resulting in better patient experiences. One of my passions is to teach digital implant dentistry to other clinicians, especially to expe­rienced implant surgeons. This case provided a unique opportunity for me to help one of my men­tors, Dr. Robert Gellin, with his first digital implant planning case. A combination of challenging esthet­ics, emergence, intraosseous residual endodontic material, and malocclusion motivated Dr. Gellin to digitally plan this single-unit anterior case as a guided surgery from start to finish.

The patient presented with an intact edentulous ridge at site No. 10 with a possible retained root fragment and residual endodontic material in that position, but with adequate ridge dimensions for implant placement.

Digital Implant Planning and Treatment

A CBCT image was captured using the Planmeca ProMax 3D Max, and a scan of the intraoral tissues was merged in the Planmeca Romexis implant planning software. A digital waxup was created in the Romexis CAD/CAM module with considerations of occlusion, gingival margin, incisal edge position, emergence profile, and prosthetic connection. This data was observed in tandem when virtually positioning the implant, with careful attention to place the implant in an ideal relationship to the labial plate of bone, adjacent anatomy, and to allow proper positioning of the implant platform for prosthetic success and future health. A virtual temporary abutment was placed and all of the planned elements were exported from Romexis to Meshmixer (Autodesk) to create the screw access hole through the planned restoration. The prosthesis was milled from CERASMART (GC America) on a Planmeca PlanMill 30 S, then cemented to the abutment to create an immediate temporary restoration. A surgical guide was designed with the Romexis guide design module, and the guide was 3D printed. A metal Steco guide sleeve was luted into the guide’s sleeve holder, and the guide was processed in preparation for clinical use. On the day of surgery, fully guided Astra twist drills (Dentsply Sirona) were used to prepare the osteotomy via flapless approach and an Astra Tech OsseoSpeed EV 3.6 x 9-mm implant (Dentsply Sirona) was inserted with torque exceeding 45 Ncm. The temporary was seated with minimal adjustment, confirming lack of occlusion. Postoperative healing was uneventful and the implant is now fully integrated.

Conclusion

The treatment plan is evolving for this patient. She is now interested in restoration of the maxillary anterior teeth to improve function and esthetics. We can be confident that because of the careful planning and accurate implant position, the potential restorative outcome will be successful. Dr. Gellin felt that this case was an enlightening experience compared to how he’d been handling implants previously. Digital implant planning, he said, is a method that allows the clinician to come as close as possible to a perfect result.Fig 1 - 6

Educational Objectives

Learning Objectives
After completing this webinar, participants will:
»      Identify the determining factors that would improve the outcome for a tooth to be saved
»      Determine if a tooth should be saved using endodontic procedures or extracted and replaced with an implant
»      Assess and implement ways that would increase the likelihood of long term tooth retention when performing root canal treatment

Abstract

Implants have changed the way patients deal with edentulism, missing teeth, and teeth that have poor to hopeless prognosis. Unfortunately, implants have more recently been seen as a substitute for teeth that are salvageable with the right treatment approach. This has specially come to light as more and more implant failures have been observed in the past 5-10 years. Implants have also forced endodontists to more critically self evaluate and determine what can be improved in performing root canal treatment in order for endodontic teeth to have an overall better long term outcome.

This presentation reviews factors that would determine whether a tooth should have endodontic treatment/retreatment or be extracted and replaced with an implant. Dr. Odabashian will discuss patient, tooth and other appropriate questions that should be asked and answered in determining whether a tooth should be kept or extracted. Finally, Dr. Odabashian will go over the lessons learned from 30 years of practice which include 10 years of general and restorative dentistry and 20 years of endodontic practice
