Perigraftitis treatment and histology: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Currently, the two diagnoses of inflammatory peri‐implant diseases are peri‐implant mucositis and peri‐implantitis. The etiology of peri‐implant mucositis and peri‐implantitis is bacterial colonization of the implant. Thus, removal of the implant should eliminate the infection and allow the inflammation to resolve. However, at least

Survival Rate and Deformation of External Hexagon Implants with One-Piece Zirconia Crowns

Metals, 2021
This study aimed to evaluate the survival rates of several external hexagon implants directly connected to zirconia crowns after thermomechanical fatigue. The deformation of the hexagons and the integrity of zirconia crowns were also evaluated.

An in vitro evaluation of marginal fit zirconia crowns fabricated by a CAD-CAM dental laboratory and a milling center

BMC Oral Health, 2019
Background Marginal fit is critical for the success and longevity of a dental restoration. Zirconia crowns can be fabricated either chair-side, in a dental laboratory or in a milling center; each can give different marginal fits results.

Are the detection and dimensions of peri‐implant buccal bone defects influenced by different implant materials and their location? An experimental cone‐beam computed tomography study

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study is to evaluate the impact of different implant materials and arrangements within the field of view (FOV) and exomass on the diagnostic accuracy and image quality of cone‐beam computed tomography (CBCT) for the detection of peri‐implant buccal bone defects of various sizes. Methods A total of 120 CBCT scans with
