Treatment of peri-implant soft tissue defects: a narrative review

Braz. oral res. (Online); 33 (supl.1), 2019
Abstract Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue e...

Avaliação histomorfométrica, imuno-histoquímica e microtomográfica da neoformação óssea ao redor de implantes de titânio com diferentes superfícies instalados em áreas de defeitos ósseos preenchidos ou não com biomaterial

O objetivo desse estudo foi avaliar a resposta óssea peri-implantar de implantes osseointegrados de titânio com dois tipos de tratamento de superfície, na presença ou não de substituto ósseo. Para tanto, foram utilizados 92 implantes dentários que foram divididos em quatro grupos de acordo com a s...

Bankart lesion repair: biomechanical and anatomical analysis of Mason-Allen and simple sutures in a swine model

ABSTRACT Objective: To evaluate the labral height and pullout resistance after the repair of Bankart lesions in the glenohumeral joint of swine models, using double-loaded anchors with two suture configurations: simple and Mason-Allen. Methods: Ten swine shoulders were used, in which Bankart lesions we...

Evaluation of Maxillary Sinus Septa Prior to Dental Implant Therapy: A Cone Beam Computed Tomography Study

SUMMARY: The objective of this study was to investigate the prevalence and location of maxillary sinus septa prior to dental implant therapy in different age groups by cone beam computed tomography (CBCT) and identify the most helpful orthogonal plane for this purpose. CBCT scans of 200 patients were sel...

The effects of subcutaneous injection of nicotine on osseointegration of machined and anodized implants in rabbits

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To evaluate the influence of subcutaneous injection nicotine in osseointegration process on different implant surfaces. Methods: Twenty-two male rabbits were distributed into two groups according to the subcutaneous injections: (1) nicotine 3 mg/day/kg and (2) 0.9 % NaCI 3 mL/day/kg,...

Stability and bone loss around submerged and non-submerged implants in diabetic and non-diabetic patients: a 7-year follow-up

Abstract To evaluate peri-implant bone loss (PIBL) and stability around submerged and non-submerged dental implants in patients with and without type 2 diabetes mellitus (T2DM). Thirty-five T2DM and non-diabetic (NT2DM) patients were included in this study. Demographic data were recorded using a question...

A comparison of different bone graft materials in peri-implant guided bone regeneration

Abstract The aim of this study was to compare the effects of hydroxyapatite (HA), deproteinized bovine bone (DPB), human-derived allogenic bone (HALG), and calcium sulfate (CAP) graft biomaterials used with titanium barriers for bone augmentation to treat peri-implant defects in rat calvarium treated by ...

Effects of hyperbaric oxygen treatment on implant osseointegration in experimental diabetes mellitus

J. appl. oral sci; 26 (), 2018
Abstract Objective To evaluate whether hyperbaric oxygen (HBO) treatment has a favorable effect on implant osseointegration in diabetic rabbits. Material and Methods An experimental diabetes model was induced in 32 New Zealand rabbits through IV injection of alloxan. After the state of diabetes had b...

Daily melatonin administration improves osseointegration in pinealectomized rats

J. appl. oral sci; 26 (), 2018
Abstract The hypothesis of this study was that the peri-implant bone healing of the group of pinealectomized rats would differ from the control group. The samples were subjected to immunohistochemical, microtomographic (total porosity and connectivity density), and fluorochrome (mineralized surface) anal...

Oral implant osseointegration model in C57Bl/6 mice: microtomographic, histological, histomorphometric and molecular characterization

J. appl. oral sci; 26 (), 2018
Abstract Despite the successful clinical application of titanium (Ti) as a biomaterial, the exact cellular and molecular mechanisms responsible for Ti osseointegration remains unclear, especially because of the limited methodological tools available in this field. Objective: In this study, we present a ...
