Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series
To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months post-treatment. The net gain in labial plate on CBCT in L1 and L2 was 3.0 mm, where 0 mm existed at pre-treatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6-9 months post-operatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics.

Flapless Postextraction Socket Implant Placement, Part 2. The Effects of Bone Grafting and Provisional Restoration on Peri-implant Soft Tissue Height &amp; Thickness - A Retrospective Study

Flapless Postextraction Socket Implant Placement, Part 2. The Effects of Bone Grafting and Provisional Restoration on Peri-implant Soft Tissue Height & Thickness - A Retrospective Study
This article presents the results of evaluating the changes in peri-implant soft tissue dimensions associated with immediate implant placement into anterior post-extraction sockets for four treatment groups: no BGPR(bone graft, no provisional restoration), PR (no bone graft, provisional restoration), BG (bone graft, no provisional restoration), and BGPR (bone graft, provisional restoration). The vertical distance of the peri-implant soft tissue was greater for grafted sites than for non-grafted ones. The facial soft tissue thickness at the gingival third was greater for grafted than for non-grafted sites and for sites with provisional restorations compared to sites without them, respectively. The net gain in soft tissue height and thickness was about 1mm. The increases in vertical and horizontal dimensions for grafted sites were between 0.5 and 1.0mm, as compared to sites with no bone graft and no provisional restoration.

Subclassification and Clinical Management of Extraction Sockets with Labial Dentoalveolar Dehiscence Defects

Subclassification and Clinical Management of Extraction Sockets with Labial Dentoalveolar Dehiscence Defects
Immediate implant therapy involving implants placed into intact Type 1 extraction sockets has become a consistent clinical technique. The classification of Type 2 extraction sockets, where the mucosal tissues are present but there is a midfacial osseous dehiscence defect, has been described according to the extent of the buccal bone plate absence. The literature has offered different techniques in the treatment of Type 2 sockets; however, the extent of the defect has never been defined or delineated.

Flapless Postextraction Socket Implant Placement in the Esthetic Zone: Part 1. The Effect of Bone Grafting and/or Provisional Restoration on Facial-Palatal Ridge Dimensional Change

Flapless Postextraction Socket Implant Placement in the Esthetic Zone: Part 1. The Effect of Bone Grafting and/or Provisional Restoration on Facial-Palatal Ridge Dimensional Change
The dental literature has reportted vertical soft tissue changes that can occur with immediate implant placement, bone grafting, and provisional restoration ranging from a gain or loss of 1.0mm. However, little is known of the effects of facial-palatal collapse of the ridge due to these clinical procedures. Based upon treatment modalities rendered, an ensuing contour change can occur with significant negative esthetic consequences. The results of a retrospective clinical cohort study evaluating the change in horizontal ridge dimension associated with implant placement in anterior postextraction sockets are presented for four treatment groups. Therefore, it is recommended to place a bone graft and contoured healing abutment or provisional restoration at the time of flapless postextraction socket implant placement.

Two Immediate Temporization Methods Exemplified: Flap vs. Punch Technique in Implant Surgery

Two Immediate Temporization Methods Exemplified: Flap vs. Punch Technique in Implant Surgery
Protocols and techniques for immediate tooth replacement in the esthetic zone have become more popular and predictable within the past decade. Two different clinical scenarios are presented where immediate temporization of implants placed into healed or augmented ridges is exemplified. The benefits of augmentation prior to implant placement and temporization are that flap elevation is not required; therefore, the blood supply to the labial plate is not compromised, thereby eliminating potential midfacial recession. In addition, the soft tissue subgingival shape of the temporary crown can be non-surgically sculpted at the time of implant placement since the patient is already anesthetized.

The Dual-Zone Therapeutic Concept of Managing Immediate Implant Placement and Provisional Restoration in Anterior Extraction Sockets

The Dual-Zone Therapeutic Concept of Managing Immediate Implant Placement and Provisional Restoration in Anterior Extraction Sockets
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this case 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.
