Limited marginal bone loss in implant‐supported fixed full‐arch rehabilitations after 5 years of follow‐up

Clinical Oral Implants Research, Volume 33, Issue 12, Page 1224-1232, December 2022., 2022
Abstract Purpose The aim of the present study was to evaluate the 5‐year results in terms of marginal bone level (MBL) around implants supporting fixed full‐arch metal‐ceramic restorations in a series of cases of patients who had lost their teeth in that dental arch because of severe periodontal disease.

Semantic decomposition Network with Contrastive and Structural Constraints for Dental Plaque Segmentation [PDF]

arXiv, 2022
Segmenting dental plaque from images of medical reagent staining provides valuable information for diagnosis and the determination of follow-up treatment plan. However, accurate dental plaque segmentation is a challenging task that requires identifying teeth and dental plaque subjected to semantic-blur regions (i.e., confused boundaries in border ...

Restoration of human tooth enamel

BMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Two‐piece zirconia implants in the posterior mandible and maxilla: A cohort study with a follow‐up period of 9 years

Clinical Oral Implants Research, Volume 33, Issue 12, Page 1233-1244, December 2022., 2022
Abstract Objectives Long‐term follow‐up observations of zirconia implants are rare. This study aimed at evaluating the clinical performance of two‐piece zirconia implants in the posterior jaws over 9 years. Materials and Methods Sixty partially edentulous patients were treated with two‐piece zirconia implants.

Expertise‐inspired artificial intelligence pipeline for clinically applicable reconstruction of tooth‐centric radial planes: Development and multicenter validation

BMEMat, EarlyView.
The expertise‐inspired AI pipeline demonstrates significant clinical utility for rapid and precise analysis of dento‐maxillofafcial CBCT and benefits for intelligent oral health management. Abstract Owing to the tooth‐centered nature of most oral diseases, the tooth‐centric radial plane of cone‐beam computed tomography (CBCT) depicts the anatomical and

DArch: Dental Arch Prior-assisted 3D Tooth Instance Segmentation [PDF]

arXiv, 2022
Automatic tooth instance segmentation on 3D dental models is a fundamental task for computer-aided orthodontic treatments. Existing learning-based methods rely heavily on expensive point-wise annotations. To alleviate this problem, we are the first to explore a low-cost annotation way for 3D tooth instance segmentation, i.e., labeling all tooth ...

The impact of cone beam computer tomography field of view on the precision of digital intra‐oral scan registration for static computer‐assisted implant surgery: A CBCT analysis

Clinical Oral Implants Research, Volume 33, Issue 12, Page 1273-1281, December 2022., 2022
Abstract Objectives Registration of intra‐oral surface scans to cone beam computer tomography (CBCT) is critical in the digital workflow for static computer‐aided implant surgery (sCAIS). This study aimed to assess the impact of CBCT field of view (FoV) on the precision of digital intra‐oral scan registration.
