Background: Matrix metalloproteinase (MMP) are involved in bone transformation at the extraction site postdental extraction. We examined the genetic association between single nucleotide polymorphisms of MMP-1 and continuous atrophy of edentulous mandible.
Methods: Buccal cells from 33 edentulous patients were collected using sterile wooden spatula and were suspended in 15 ml falcon tubes containing 1.5 ml of cell lysis buffer, without proteinase K. The cells were transported to the laboratory on ice and were stored at -20°C until being processed.
Results: Of the samples analyzed, 26 edentulous patients (78.8%) carried 2G allele, while 7 of them (21.2%) carried 1G allele.
Conclusion: The patients with the alveolar bone resorption exhibited more of 2G allele while only 21.2% of them showed 1G allele, associated with excessive atrophy of edentulous mandible. This study may provide genetic background to identify susceptible individuals prone to develop jawbone atrophy after dental extraction.

Objective: This study aimed to explore the feasibility and reliability of measuring the vertical dimension of occlusion/rest (OVD/RVD) on 3D facial scans of edentulous patients.
Methods: Nineteen edentulous participants rehabilitated with complete removable dental prostheses (CDs) participated in this study. Analog measurements (control) were obtained directly on the face for each participant with the jaws positioned at the rest position (without CDs, RVD) and at central occlusion (OVD), between the facial landmarks: Glabella (G) and Soft Pogonion (SP), Pronasale (PN) and SP, and Subnasale (SN) and SP.

Background and objective Alveolar ridge defects in partially edentulous patients present significant challenges in prosthodontic treatment planning. Seibert's classification system provides a structured approach to categorizing these defects based on the buccolingual and apico-coronal dimensions of the ridge. Accurate classification is crucial for determining appropriate treatment strategies for implant placement, fixed prosthesis, or tissue augmentation.

: Mandibular fractures are among the most common facial injuries. Bilateral fractures of the mandibular body region (BBMFs), however, are rare. The aim of this retrospective study was to analyze the characteristics, surgical management, and outcomes of BBMFs in a third-level trauma center in northern Italy.

Unlabelled: Given the rising global population of older adults and their association with edentulism and the use of complete removable prostheses [CRP], it is imperative to pursue solutions for issues such as the relationship between poor diets and masticatory deficiency.
Objective: To examine the research on the efficacy of dietary counseling in enhancing mastication and nutrition in older adults with CRP.
Methods: A systematic literature review was performed in the PubMed, Trip, and Web of Science databases.

Sandblasting and acid etching are common procedures used to treat implant surfaces, enhancing osseointegration and improving clinical success rates. This clinical study aimed to evaluate the long-term outcomes of sandblasted and acid-etched implants. A total of 303 implants were placed in 114 partially and totally edentulous patients using a two-stage surgical technique and an early loading protocol (6-8 weeks).
