Retrospective Evaluation of Crestal Bone Changes Around Implants With Reduced Abutment Diameter Placed Non-Submerged and at Subcrestal Positions: The Effect of Bone Grafting at Implant Placement Retrospective Evaluation of Crestal Bone Changes Around Implants With Reduced Abutment Diameter Placed Non-Submerged and at Subcrestal Positions: The Effect of Bone Grafting at Implant Placement

Summary:

One method to measure the success of dental implant treatment is to evaluate marginal peri-implant bone-level changes and stability over time. The location of the fixture–abutment interface (FAI) can be of major importance when the goal is to construct esthetic restorations. In these situations the FAI is often placed in a more apical position to create an ideal emergence profile for the prosthetic construction. However, several animal studies have reported that placement of the FAI in a subcrestal position may result in peri-implant marginal bone loss. The aim of the present study is to evaluate the effect of bone grafting of the defect between the bone crest and the coronal aspect of the implant for implants with reduced abutment diameters placed non-submerged and in subcrestal positions.

Long-Term Block Graft Stability in Thin Periodontal Biotype Patients - A Clinical and Tomographic Study
Autogenous block grafting seems to be a predictable treatment modality to reconstruct alveolar ridge defects in the long term. A thin periodontal biotype did not seem to affect the volume of transplanted bone for the population studied.

Long Term Follow-Up of Dental Implants Placed in Autologous Onlay Bone Graft

Long Term Follow-Up of Dental Implants Placed in Autologous Onlay Bone Graft
The aim of this study was to evaluate the efficacy of autologous intraoral onlay bone grafting (OBG) in correlation with long-term survival rates of dental implants placed in the augmented bone. A retrospective study was conducted on 214 patients who received a total of 633 dental implants placed in 224 autologous intraoral block OBG augmentations, combined with Bio-Oss – mixed with platelet-rich plasma (PRP) and covered by platelet-poor plasma (PPP) – as scaffold, with a follow-up time up to 137 months. We suggest that augmentation of severely atrophied jaw bone through the placement of horizontal and/or vertical intraoral OBGs in combination with Bio-Oss saturated with PRP and covered by PPP should be considered a reliable, safe, and very effective surgical technique for obtaining high bone graft survival rate and high long-term implant survival rate.

Early Implant Placement with Contour Augmentation - Biologic Rationale, Surgical Technique & Long-Term Results Premium Member Content

Early Implant Placement with Contour Augmentation - Biologic Rationale, Surgical Technique & Long-Term Results
Today, the timing of implant placement post-extraction in the esthetic zone is considered an important factor which influences the esthetic treatment outcome. One of these options is early implant placement after 4 to 8 weeks of soft-tissue healing. The purpose of this presentation is to present data and to analyze the stability of esthetic treatment outcomes in patients following single-tooth replacement in the anterior maxilla using the concept of early implant placement with simultaneous contour augmentation. Special emphasis will be placed on assessing the stability of the facial mucosa, since it directly depends on the stability of successful contour augmentation by GBR and to compare it to currently utilized immediate techniques like Dual Zone Therapy (Chu & Tarnow) and Partial Extraction Therapies (Salama & Gluckman).

Challenges & Management of Peri-Implant Pink Esthetics in Anterior Implant Therapy
When considering implant therapy in the esthetic zone, replicating the natural soft tissue frame may present challenges for the treating clinician. This presentation will highlight different clinical scenarios in which the lack of hard and soft tissue volume may pose difficulties in achieving ideal peri-implant esthetics, in addition to available clinical strategies on how to manage and minimize hard and soft tissue deficiencies when dealing with implant therapy in the esthetic zone.

The Dual Zone Approach to Tooth Replacement in the Esthetic Zone Premium Member Content

The Dual Zone Approach to Tooth Replacement in the Esthetic Zone
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this presentation will enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device. Long term follow up and evidence from scientific literature to support this concept will be described.

Positive & Negative Factors in Stem Cells & Wound Healing: Solutions for Long Term Stability Premium Member Content

Positive & Negative Factors in Stem Cells & Wound Healing: Solutions for Long Term Stability
The main factor for soft and hard tissue healing is the speed and quality of new vascularization. This lecture will present all the positive and negative factors who control the angiogenesis, blood supply and bone metabolism: -Biological factors as vit. D and cholesterol have to be checked before the surgery -The management of the flaps with sutures is one the main factor for the bone and soft tissue maintenance.. -The soft brushing technique is a new technique which increases the flap without periosteal incision nor bleeding. -Careful Implant placement without too much torque, specially in cortical bone or grafted bone at the re-entry.. -The A-PRF liquid and i-PRF are solutions to reduce the mobility of the granules (sticky bone) with an improvement of angiogenesis The use of growth factors is a stimulation of angiogenesis. The prevention of the negative factors will allow us to achieve the long term stability.
