Soft tissue alterations in patients with reduced height of the occlusion

Desislava Konstantinova, Anna Nenova-Nogalcheva


Introduction: In the field of dental medicine there is a growing interest in facial aesthetics, which is becoming one of the goals of the modern prosthetic treatment. The soft tissue profile has been studied by scientists because it occupies a primary place in building the aesthetic appearance of the face.

Aim: The aim of this article is to examine the soft tissue profile of patients with reduced occlusion height.

Materials and Methods: Twenty patients were studied. They were separated into two groups. The first group included 11 edentulous patients, and the second group included nine patients with natural dentition with different degree of abrasion. The examination of the patients was based on two indicators: 1. convexity of the nose and 2. contour of sulcus nasolabialis. Statistical analysis was performed using SPSS (IBM SPSS Statistics 22.0) software.

Results and Discussion: The results showed that in the group with edentulous patients men’s average convexity of the nasal contour is much above the accepted norm (25.7 mm for males and 24 mm for females). In the group of patients with early-stage abrasion, the mean showed extremely close values to the accepted norm. There was a statistically significant relationship between nasal convexity and loss of occlusion height (r = 0.302, p < 0.05). According to the other indicator studied by us, in the group with edentulous patients, the average was 1.15 ± 0.05 mm. It is 1.3 ± 0.5 mm in female and 1.0 ± 0.3 mm in male. There was statistically significant relationship between the degree of nasolabial sulcus expression and the height of occlusion (r = 386, p < 0.05).

Conclusion: The degree of recovery of the patient's soft tissue profile is also important for the success of the prosthetic and the treatment plan of entire masticatory apparatus.
