Purpose: The aim of the study is to evaluate the bucco-lingual volumetric tissue change that occurs in the 6 months time frame following flapless single-tooth extraction in the molar area without placing any filler in the alveolus. Materials and Methods: Patients in need of an extraction of a first or second molar in the mandible or maxilla were consecutively recruited. Immediately before the extraction (Baseline) and two, four, and six months after extraction an alginate impression of the area was taken and immediately poured with orthodontic gypsum. The bucco-palatal dimension (BPD) was measured with an electronic caliper on the study casts at 1 mm, 3 mm, and 5 mm apical to the free gingival margin and the horizontal volumetric changes were compared between baseline and two, four, and six months post-extraction. Results: A total of 65 patients were examinated. Changes in the mean horizontal ridge dimension were recorded. After 6 months the BPD diminished at 1 mm, 3 mm and 5 mm distance from the free gingival margin respectively of 5.91 ± 0.158 mm (p-value <0.01), ( - 52.13%), 4.68 ± 0. 178 mm (p-value <0.001) (- 47.07%), and 3.75 ± 0.178 mm (p-value <0.001) (- 37.81%). Conclusions: The observed volumetric soft tissue changes appeared to affect significantly the original bucco-lingual alveolar dimension in the 6 months short term follow-up after single tooth extraction in the molar area.
