ABSTRACT
Aim of the study This study aimed to analyze the coronal morphological changes in molars and premolars associated with dental abrasion secondary to FPDs. Materials and methods The study included 35 patients (aged 29-67 years) who presented at the Faculty of Dentistry, Ovidius University in Constanța between February and October 2024. Patients had FPDs and abrasion lesions on opposing natural lateral teeth. Clinical examinations documented the topography and severity of dental abrasion, complemented by intraoral photography. Data were analyzed using descriptive and analytical statistical methods, including Pearson correlation tests. Results The study found that 63% of participants were female, with a 1.7:1 female-to-male ratio. Unilateral mastication was most common (48.57%), and lateral edentulism predominated (57.14%). The most frequently used FPD materials were semi-physiognomic metal-acrylic (38%) and fully physiognomic metal-ceramic (30%). Buccal cusps exhibited greater abrasion than lingual cusps, with mandibular teeth showing more severe wear (grade 4 abrasion) than maxillary teeth. The correlation between FPD follow-up and abrasion severity was significant (Pearson = 0.904, Sig. = 0.045), indicating that prolonged prosthetic use exacerbates tooth wear. Conclusions The study highlights the progressive nature of dental abrasion in patients with FPDs, with mandibular teeth exhibiting more severe morphological changes. Findings emphasize the need for optimized prosthetic materials and occlusal adjustments to minimize long-term wear. Future research should focus on material innovations and preventive strategies to enhance FPD longevity while preserving natural dentition integrity.
