Abstract

Purpose: The aim of this prospective clinical cohort study is to evaluate how the use of ovate pontic alongside alveolar ridge preservation (ARP) contributes to soft tissue preservation when placed immediately post-extraction into a socket with or without intact buccal bone plate in the esthetic zone.

Materials and methods: Twenty-three patients with a non-restorable tooth in the maxillary esthetic zone bound by natural adjacent teeth were recruited for the study. At the time of extraction, patients were assigned to three groups, Group A (type I socket with ARP), B (type II socket with ARP), and C (type II socket with ARP and membrane). Following flapless extraction, an ovate pontic with ARP was placed. Impressions were taken before extraction, and at 3- and 6-month follow-up visits. Master casts were created to measure dimensional alterations. Descriptive statistical analysis compared changes in linear and volumetric measurements over the follow-up period.

Results: After 6 months, Group A showed mean dimensional changes of -1.28 ± 0.75 mm in width, -1.19 ± 0.61 mm in height, and -30.51 ± 17.55 mm3 in volume. Group B had changes of -1.07 ± 0.48 mm in width, -1.12 ± 0.51 mm in height, and -23.36 ± 7.74 mm3 in volume. Group C experienced changes of -1.43 ± 0.41 mm in width, -0.98 ± 0.32 mm in height, and -31.27 ± 9.59 mm3 in volume.

Conclusions: Utilization of an ovate pontic provisional restoration in conjunction with ARP minimizes post-extraction ridge alteration and maintains natural morphology, providing a stable prosthetic foundation for fixed restorations, regardless of bone plate presence.

期刊介绍: The Journal of Prosthodontics promotes the advanced study and practice of prosthodontics, implant, esthetic, and reconstructive dentistry. It is the official journal of the American College of Prosthodontists, the American Dental Association-recognized voice of the Specialty of Prosthodontics. The journal publishes evidence-based original scientific articles presenting information that is relevant and useful to prosthodontists. Additionally, it publishes reports of innovative techniques, new instructional methodologies, and instructive clinical reports with an interdisciplinary flair. The journal is particularly focused on promoting the study and use of cutting-edge technology and positioning prosthodontists as the early-adopters of new technology in the dental community.
