Clinical Application of Alveolar Ridge Preservation Techniques in the Orthodontic Space Closure to Prevent Gingival Invagination

Abstract

Abstract: Objective: To evaluate the feasibility of alveolar ridge preservation techniques and the effects on gingival invagination during orthodontic space closure after tooth extraction. Methods: Three adult patients with 6 pairs of teeth were involved and first premolars were symmetrically extracted. One side was randomly selected to implant bio-oss bone material and cover bio-gide collagen membrane (experiment group), while the other side underwent the conventional orthodontic process (control group). After six-week treatment, the incidence of gingival invagination was evaluated using periodontal probe, respectively. Results: In the control group, gingival invagination occurred in the maxilla of one patient and mandible of all patients. However, there was no gingival invagination in the experimental group. Conclusion: Site preservation technique could effectively avoid the atrophy of tooth sockets and gingival invagination.

Key words: Gingival invagination, Alveolar ridge preservation technique, Tooth extraction, Alveolar bone, Orthodontic space closure
