Assessment of Supraeruption of Teeth Affecting Prosthodontics Rehabilitation in Different Segments of Opposing Arch

Abstract

Loss of vertical space due to supraeruption of teeth in opposing arch can make it difficult to replace missing teeth with implants, removable or fixed partial dentures. Objective: In the current study, we sought to evaluate and quantify the quantity of supraeruption of teeth in different segments of arch during prosthodontics rehabilitation with different prostheses. Methods: This cross-sectional study included 140 subjects with unopposed teeth from prosthodontics department. Data were collected by pre-structured proforma. Amount of supraeruption were recorded in millimeters on dental casts after obtaining impressions. Teeth involved in supraeruption like molars and others on right/ left side in either maxillary / mandibular arch, were noted from study casts and were assessed. Data were analyzed using (SPSS version 20). Results: For the study, 140 individuals in total were selected (54 males and 86 females). This study observed dental caries as the main cause of tooth loss. Mean age of patients were 43 years. Mean super-eruption values for subjects were 2.22mm with standard deviation of 0.66mm. More number of supraerupted teeth were found in unopposed maxillary arch than the mandibular. Highest frequency of super-eruption was found in molars areas and on right side of the arch. Conclusions: It was concluded that unopposed teeth lead to over-eruption of antagonists. Differences were recorded between sites, type and status of supra-eruption. Current study observed that highest ratio of super-eruption recorded in maxillary arch, in molar region and on the right side of arch.

Full-Arch Implant-Supported Restorations: Hybrid versus Monolithic Design

“…• Clinical observations and considerations: Clinical observations suggest that monolithic restorations exhibit favorable wear properties, providing minimal abrasiveness to opposing dentition [26]. The hardness and structural integrity of monolithic materials contribute to reduced wear rates on natural teeth when compared to hybrid restorations.…”

“…• However, hybrid materials, particularly those with softer veneering layers or varying compositions, might exhibit increased wear characteristics, potentially causing accelerated wear on opposing natural teeth [26]. The differential wear properties between hybrid layers and natural dentition could lead to uneven wear patterns and potentially compromise the longevity of the restoration.…”
