Crestal Bone Stability around Implants with Horizontally Matching Connection after Soft Tissue Thickening: A Prospective Clinical Trial

Abstract

It can be concluded that thin mucosal tissues may cause early crestal bone loss, but their thickening with allogenic membrane may significantly reduce bone resorption. Implants in naturally thick soft tissues experienced minor bone remodeling.

Influence of Soft Tissue Thickness on Peri‐Implant Marginal Bone Loss: A Systematic Review and Meta‐Analysis

“…Four articles are RCTs 27–30 and four are comparative controlled trials 22,31‐33 . Of the eight articles included, three were further excluded from meta‐analysis of MBL for the following reasons: 1) no comparison between thick and thin tissues (both groups presented with thin mucosa); 22 2) no comparison between thick and thin tissues (both groups presented with thick mucosa); 30 and 3) no reporting of standard deviation for MBL 31 …”

“…Of the five articles included in the meta‐analysis, four used 2 mm as a cutoff point to divide between thin and thick tissue, 27‐29,32 and one study used 3 mm 33 . Two articles 29 , 32 divided tissue thickness into three different categories: thin, thin (thickened), and thick. Both of them used an allograft for increasing tissue thickness at time of implant placement.…”

“…Five studies 27‐29,32,33 reported data on MBL of implants with thin and thick soft tissue. Of those five, two 29 , 33 reported that the implants were placed at crestal bone level; two 27 , 32 at supracrestal bone level; and one 28 at both crestal and supracrestal bone levels. The statistical results from each of the selected studies were converted into effect sizes and combined in the meta‐analysis.…”

The Dermal Apron Technique for Immediate Implant Socket Management: A Novel Technique

“…The establishment of biologic width coronal to the alveolar crest likely reduced hard tissue loss in healed sites, as demonstrated by Linkevicius. Using a different dermal allograft (Alloderm; BioHorizons), Linkevicius and colleagues . showed peri‐implant soft tissues thinner than 2.0 mm resulted in significantly greater marginal bone loss compared to those implants surrounded by naturally thicker (>2.0 mm) mucosa and implants augmented with a dermal allograft.…”

Advanced Esthetic Management of Dental Implants: Surgical and Restorative Considerations to Improve Outcomes

“…The augmentation of soft tissue can significantly prevent loss of peri‐implant horizontal and vertical tissue dimensions . The importance of soft tissue thickness can also play a crucial role in the maintenance of crestal bone . This is accomplished with autogenous or allogeneic grafts (Figure A and B).…”
