The ABC Protocol in the Esthetic Zone: A Comprehensive Surgical & Prosthetic Approach
the purpose of this article is to present a surgical and restorative protocol for the replacement of missing teeth in the esthetic zone. The ABC protocol consists of digitally guided implantation, autogenous bone graft, followed by bovine bone xenograft and connective tissue graft. Autogenous bone is placed in contact with the implant surface to induce osseointegration; bovine bone xenograft is then applied to augment the ridge dimension and provide long-term stability. Connective tissue is used to provide additional volume. The ABC biomaterial sequence offers favorable hard and soft tissue dimensions and immediate provisional restoration predictably leads to an esthetically pleasing definitive prosthesis.
Palatal Augmentation Technique: A Predictable Method to Increase the Palatal Connective Tissue at Donor Sites - A Consecutive Case Series
The palatal masticatory mucosa between the canine and first molar is the main source of connective tissue graft (CTG) for use in periodontal plastic surgery. The purpose of this study was to evaluate the palatal augmentation technique (PAT) to increase the palatal connective tissue donor area using a collagen sponge inserted between the palatal flap and bone. The 26 patients enrolled in this study were referred for root coverage and ridge augmentation procedures. All patients lacked adequate donor palatal tissue thickness. The PAT uses a full thickness flap and bone. The palatal thickness was clinically assessed before and after collagen sponge insertion. A Manual probe was inserted in the mucosal surface perpendicular to the long axis of each tooth approximately 6mm from the gingival margin. Probing depth and recession were also recorded. Treatment with PAT resulted in a statistically significant increase in the palatal thickness.
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.
Crestal Bone Stability around Implants with Horizontally Matching Connection after Soft Tissue Thickening: A Prospective Clinical Trial
It has been shown that thin mucosal tissues may be an important factor in crestal bone loss etiology. Thus,
it is possible that mucosal tissue thickening with allogenic membrane might reduce crestal bone loss.
Purpose: The purpose of this study was to evaluate how implants with traditional connection maintain crestal bone level
after soft tissue thickening with allogenic membrane.
After 1-year follow-up, implants in group A had 1.65 1 0.08-mm bone loss mesially and 1.81 1 0.06 mm distally.
Group B had 0.31 1 0.05 mm mesially and 0.34 1 0.05 mm distally. C group implants experienced bone loss of 0.44 1
0.06 mm mesially and 0.47 1 0.07 mm distally. Differences between A and B, and A and C were significant both
mesially and distally, whereas differences between B and C were not significant mesially and distally
Developing Optimal Peri-Implant Papillae within the Esthetic Zone: Guided Soft Tissue Augmentation
Osseointegrated dental implants have enjoyed long-term success in the rehabilitation of totally edentulous patients. Every aspect of traditional treatment planning protocols continues to be re-evaluated and updated to better incorporate the benefits of osseointegration into clinical practice. This is particularly evident as dentistry has committed to fully integrating this approach into the more varied and demanding environment of the partially edentulous patient. Along with the many benefits of added predictability and enhanced options, the ever-evolving role of osseointegrated implants in the treatment pf the partially edentulous jaw has also created new challenged. Unlike the fully edentulous individual who maintains the implant-restorative interface beyond the lip perimeter, many partially edentulous patients undergo the transition within the esthetic zone.
