Esthetic Correction of Gingival Recession Using a Modified Tunnel Technique and an Acellular Dermal Connective Tissue Allograft
Esthetic correction of gingival recession is an important goal of periodontal therapy. This article describes a surgical technique that combines a modified tunnel technique and an acellular dermal connective tissue allograft. With the aid of vertical incisions, a tunnel is created under the buccal mucosa of the affected tooth. These incisions enable easy access for graft placement and create mobility for gingival coronal positioning. The use of an accelular dermal connective tissue allograft eliminates the need for a surgical palatal donor site. This minimizes post-surgical complications.
Mucosal Coronally Positioned Flap for the Management of Excessive Gingival Display in the Presence of Hypermobility of the Upper Lip and Vertical Maxillary Excess: A Case Report
Excessive gingival display is a frequent
finding that can occur because of various
intraoral or extraoral etiologies. This report describes
the use of a mucosal coronally positioned flap for the
management of a gummy smile associated with vertical
maxillary excess and hypermobility of the upper
lip. For patients desiring a less invasive
alternative to orthognathic surgery, the mucosal coronally
positioned flap is a viable alternative. We demonstrate
short-term successful use of this technique
for the management of excessive gingival display in
the presence of slight vertical maxillary excess and
hypermobility of the upper lip. Long-term follow-up
studies are needed to determine stability of the results.
Bonding Lithium Disilicate Ceramic to Feather-Edge Tooth Preparations: A Minimally Invasive Treatment Concept
The purpose of this study is to report short-term clinical outcome of a new minimally invasive prosthetic approach utilizing monolithic lithium-disilicate full crowns bonded to feather-edge tooth preparations. This procedure can be considered a further option for the conservative restorative treatment of single elements where a full crown is required.
Influence of Thin Mucosal Tissues on Crestal Bone Stability Around Implants With Platform Switching: A 1-year Pilot Study
The aim of this pilot study was to determine what effect thin mucosal tissues can have on crestal bone stability around implants with platform switching. Within the limitations of this pilot study it can be concluded that implants with platform switching did not preserve crestal bone better in comparison with implants with traditional implant-abutment connection if, at the time of implant placement, thin mucosal tissues were present.
Management of Retrograde Peri-Implantitis by Apical Resection and Guided Bone Regeneration in Adjacent Maxillary Implants
Retrograde peri-implantitis (RPI) is defined as a clinically symptomatic periapical lesion that develops
shortly after implant insertion while the coronal portion of the implant sustains a normal bone-to-implant interface. A 61-year-old male was screened and evaluated for three maxillary anterior implants placed 10
years previously. Evaluation included a thorough periodontal and dental exam, radiographs, and cone-beam computed tomography. Probing depths around all implants ranged from 2 to 4 mm with no bleeding on probing/mobility. The apices of
implants #8 and #9 exhibited radiolucencies, and a draining fistula was associated with implant #8. Treatment consisted of sectioning and removal of the affected portion of the implants and collection of a specimen for histopathologic examination.
Resection of the apical portion of implants is a viable treatment modality in the management of RPI.
