Background:Tooth wear is a multifactorial condition that results in the loss of hard dental tissue. Physiological wear does not usually result in any subjective symptoms. Pathological abrasion of hard dental tissues is accompanied by both morphological and functional disorders of the dental system
Objective: To evaluate the functional and aesthetic results of complex treatment of pathological abrasion of dental hard tissues.
Materials and methods: This is a prospective controlled study that included 82 patients with a clinically confirmed diagnosis of Increased tooth wear of the first and second degree of severity (from 2020 to 2024). The age of the patients ranged from 34 to 68 years (48 men, 34 women).
The examination of patients included: collecting complaints and identifying concomitant somatic diseases, X-ray examination, photographs of the patient's face, bite height, and nasolabial folds. Distribution of the group:
Group 1 included patients with the first degree of hard tissue loss 47 (29 men, 18 women)
Group 2 included patients with the second degree of hard tissue damage 35 (21 men, 14 women).
During examination, patients complained of aesthetic defects caused by tooth wear and discoloration, discomfort when closing, chewing and phonetic disorders, typical symptoms of TMJ dysfunction, such as pain and crunching in the joints, fatigue of the masticatory muscles and muscle pain, displacement of the lower jaw to the side during vertical movements, a feeling of distension in the ears, headaches and bruxism.
In patients of group 1: tooth wear was restored with orthopedic structures.
In patients of group 2: temporary prosthetic structures and occlusal splints were used to normalize occlusal relationships in case of TMJ and masticatory muscle dysfunction. Gradual raising of the bite was carried out by means of a set of kappa-splints for 14 days, 1 month and 3 months from 1.0 to 5.0 mm until complete restoration of the occlusal height depending on the severity of pathological abrasion of teeth, abrasion of teeth restored by orthopedic structures. Dynamic observation of the clinical condition of the prosthesis structure was carried out in the following periods: 1 week, 1, 6,
12, 24 months,assessment of the condition of the performed restorations were recorded in the medical record of the dental patient.
Results:Clinical radiological results showed satisfactory results and are encouraging in patients of groups 1 and 2. After treatment in patients of groups 2, according to the analysis of the lateral teleroentgenogram of the head, an increase in
the height of the lower third of the face is noted, in 28 patients the nasolabial folds were smoothed out. Patients were satisfied with the aesthetic and functional results of the treatment
Conclusions: The results of the study showed that treatment using occlusal splints at the preparatory stage in patients of group 2 with occlusion disorders due to pathological abrasion of hard dental tissues and restoration with orthopedic
structures is relevant for normalizing the occlusal relationships of the jaws and this complex treatment method provides a good aesthetic and functional result.
