Bacterial Colonization and Dental Implants: A Microbiological Study

Abstract Objective: To compare colony forming unit (CFU) of oral bacterial from buccal mucosa and lingual buccal tongue among patients with a dental implant and normal oral hygiene individuals without a dental implant. Material and Methods: Twenty-six individuals with a dental implant and twenty-six i...

Three-dimensional misfit between Ti-Base abutments and implants evaluated by replica technique

J. appl. oral sci; 28 (), 2020
Abstract An important factor affecting the biomechanical behavior of implant-supported reconstructions is the implant-abutment misfit. Objective: This study evaluated the misfit between Ti-Base abutments and implants by means of polyvinyl siloxane replica technique using microcomputed tomography (μ...

Gingival fibroblasts behavior on bioactive zirconia and titanium dental implant surfaces produced by a functionally graded technique

J. appl. oral sci; 28 (), 2020
Abstract Adding a biological apatite layer to the implant surface enhances bone healing around the implant. Objective This study aimed to characterize the mechanical properties and test human gingival fibroblasts behavior in contact with Zirconia and Titanium bioactive-modified implant materials. Meth...

Biomechanical and morphological changes produced by ionizing radiation on bone tissue surrounding dental implant

J. appl. oral sci; 28 (), 2020
Abstract Objective: This study analyzed the effect of ionizing radiation on bone microarchitecture and biomechanical properties in the bone tissue surrounding a dental implant. Methodology: Twenty rabbits received three dental morse taper junction implants: one in the left tibia and two in the right ti...

Management of the maxillary sinus complications after dental implantation: a systematic review and meta-analysis

Braz. dent. sci; 23 (2), 2020
Background and aim: Endoscopic sinus surgery owing to its satisfactory prognosis and low complication is considered as the first line of surgical procedure. Implant failure is often reported despite efforts in recent years. The purpose of this study was to review the factors leading to side effects in de...

Atrophic jaw fracture and predictability in oral rehabilitation: case report

Braz. dent. sci; 23 (3), 2020
Introduction: The treatment of atrophic jaw fractures requires extensive knowledge by the maxillofacial surgeon. The correct diagnosis and planning optimize the possibility of oral rehabilitation towards many possible alternatives. The difficulty in repairing these fractures ma...

Failure of miniscrews installed in maxilla and mandible: a systematic review and meta-analysis

Braz. dent. sci; 23 (3), 2020
Objective: The aim of this systematic review was to compare the clinical failure rate of orthodontic miniscrews in maxilla and mandible. Material and Methods: Randomized controlled trials of patients in orthodontic treatment, which required miniscrews for or...

Adaptación de pilares rectos sobre implantes con conexión hexagonal interna y externa por microscopía electrónica de barrido

Odontología (Ecuad.); 22 (1), 2020
En implantología oral, ha sido motivo de investigación y constante evolución la interfase implante-pilar, princi-palmente desde el punto de vista biomecánico y biológico. Objetivo: Valorar el espacio o “gap” en la interfase implante-pilar en implantes de conexión hexagonal interna y externa por...

Ultrastructural analysis of bone formation around dental implants in nondiabetic rats, severe diabetics not controlled and controlled with insulin
