To evaluate the volumetric changes and peri-implant health at implant sites with without previous soft tissue grafting over a 5-year observation period.In 18 partially edentulous patients, dental implants were placed in esthetic zone (15-25) simultaneous guided bone regeneration, followed by submerged healing. During healing phase, eight patients (test) received subepithelial connective graft, whereas 10 (control) did not receive any augmentation. Subsequently, abutment connection was...
The aim of this study was to comprehensively assess the literature in terms effect peri-implant mucosal thickness on esthetic outcomes and efficacy soft tissue augmentation procedures increase with autogenous grafts or substitutes.Two systematic reviews (SR) were performed prior consensus meeting following questions. Review 1, focused question: In systemically healthy patients an implant-supported fixed prosthesis, what is influence thin as compared thick mucosa outcomes? 2, question 1:...
ABSTRACT Aim To compare the histological structure of biopsies from anterior and posterior regions human palate in order to gain insights into potential differences soft tissue harvesting sites. Methods This comparative study involved 20 participants, each whom four samples palatal mucosa were collected. The histologically processed subsequently analysed. thickness epithelium, lamina propria, length rete pegs measured using a microscope. In addition, parameters such as collagen fibres,...
To compare two ridge preservation techniques and spontaneous healing in terms of soft tissue thickness, contour changes, handling months after tooth extraction.Thirty-six patients were included with buccal bone plate dehiscences up to 50% single-tooth extraction the esthetic zone. They randomly assigned receive one three procedures: a deproteinized bovine mineral 10% collagen (DBBM-C) covered matrix (DBBM-C/CM), DBBM-C alone, or (SH). Two later, status was assessed, thickness mucosa measured...
To test whether or not the use of a xenogeneic block loaded with recombinant human bone morphogenetic protein-2 (rhBMP-2) results in different quantity and quality compared to an autogenous block.Twenty-four patients insufficient volume for implant placement were randomly assigned two treatment modalities: rhBMP-2 (test) (control). The horizontal ridge width was evaluated prior augmentation, after augmentation at 4 months. Patient-reported outcome measures (PROMs) assessed suture removal...
Abstract Objective To evaluate volumetric changes of soft tissues at pontic sites in patients treated with or without tissue grafting over an observation period 10 years. Materials and Methods A total 17 receiving a tooth‐borne fixed dental prosthesis ( FDP ) were enrolled this study. Nine received subepithelial connective graft (SCTG) the site (test). Eight continued (control). Baseline impressions taken after delivery final Casts scanned digital images superimposed for linear measurements:...
Abstract Objectives To analyse the soft tissue morphology under healthy and experimental mucositis conditions comparing zirconia titanium implants. Methods Forty‐two patients with two adjacent missing teeth received one (Zr) (Ti) implant, mesial distal position randomized. At 3 months, half of were instructed to continue (healthy; h) other omit (experimental mucositis; m) oral hygiene around implants for weeks. Clinical parameters evaluated before after phase, a biopsy was harvested. Mixed...
Abstract Aim The aim was to evaluate the performance of implants placed with simultaneous guided bone regeneration (GBR) using resorbable or nonresorbable membranes compared in pristine without after an observation period 22–24 years. Material and Methods patient cohort this clinical trial treated from 1994 1996. Dehiscence defects were GBR by either collagen (BG) ePTFE (GT). Implants served as a control (CT). Clinical parameters, marginal levels, technical outcomes evaluated following...
Abstract Objectives To test whether or not the use of a xenogeneic block loaded with rhBMP‐2 results in superior radiological and profilometric outcomes compared to an autogenous bone block. Materials methods Twenty‐four patients randomly received (test) (control) for primary augmentation. The ridge width (RW) was evaluated by means CBCT scan after augmentation surgery at 4 months, prior implant placement. Surface scans were taken months analyses. Data analyzed Wilcoxon‐signed rank test,...
Abstract Objectives The aim of the study was to test whether or not use a polyethylene glycol (PEG) hydrogel with without addition an arginylglycylaspartic acid (RGD) sequence applied as matrix in combination hydroxyapatite/tricalciumphosphate (HA/TCP) results similar peri‐implant bone regeneration traditional guided procedures. Material and methods In 12 beagle dogs, implant placement were performed 2 months after tooth extraction maxilla. Two standardized box‐shaped defects bilaterally...
To evaluate the volumetric changes and peri-implant health at implant sites with without previous soft tissue grafting over a 12-year observation period.Eighteen patients received dental implants simultaneously guided bone regeneration in esthetic zone (15-25) for rehabilitation. Three months following placement, 8 (test) an additional subepithelial connective graft, whereas 10 (control) did not receive any treatment. One week after prothesis delivery 5 12 years follow-up examination,...
To assess the clinical, radiographic and patient-reported outcomes (PROMs) of posterior zirconia titanium implants at 1 year implant loading.
Abstract Aim The aim of this study was to test whether or not a collagen matrix can improve early wound healing compared spontaneous based on histological and immunohistologic analyses. Methods In 20 volunteers, 6 mm punch biopsies were harvested at the palate. A xenogeneic ( XCM ) sutured in one site; other left untreated (control). Biopsies with diameter 8 subsequently obtained 4, 8, 15 29 days analyses performed. Results At day bed keratinization amounted 12.4 ± 7.5% (control) 18.0 10.2%...
Abstract Aim To compare subepithelial connective tissue grafts (SCTG) versus guided bone regeneration (GBR) for the treatment of small peri‐implant dehiscence defects in terms profilometric (primary outcome), clinical, and patient‐reported outcome measures (PROMs). Methods Sixteen patients who presented with buccal dehiscences (≤3 mm) following single implant placement were recruited. Following placement, defect sites randomly treated either a SCTG or GBR. Six lacked after assigned to...
