Abstract
Composite veneers, crowns, and inlay bridges after orthodontic therapy can reshape the dental arch. The main emphasis is given on esthetic appearance of the patient and protection of healthy teeth. The aim of the study was to evaluate the long-term treatment stability.
49 composite veneers, crowns and inlay bridges (20 patients) were inserted on the frontal teeth as a part of reshaping and reorientation of teeth after orthodontic therapy; diasthemic closure, microdontia of lateral incisors, reshaping of canines, anodontia of lateral incisors, etc. Based on ADA recommendation a special card was prepared containing relevant information on the patients. Used materials were: Charisma, Artglass, (Kulzer) Ribbond, (Sigma Dental Systems) Targis, Vectris, (Ivoclar). Baseline examination was made one week and three years after therapy. Clinical assessments were carried out in accordance with the US Public Health Service System. The follow-up included: marginal ridge, marginal adaptation, anatomic form, caries presence, color match, cavo surface margin discoloration, surface smoothness and postoperative sensitivity.
In the three year period, marginal ridge contour and adaptation were excellent (100% alfa). Anatomic form was destroyed in 18.7%. The general contour of the restoration followed the overall contour of the teeth in 81.3%. In our study no evidence of caries was found. The color match was darker and translucent in 31.2 %, and marginal discoloration was seen in 12.5%. The entire surface of each restoration was smooth with marked spot relief in 62.5%.
The results demonstrate that composite resin and reinforced polymers are an effective method for long-term stable treatment
