“…Explanations regarding the development of gingival ingrowths include increased proliferation of connective tissue and epithelium, to a change in bone topography and/or morphology, and the impaired development of free gingival and transseptal fibers, or to a bone fracture while the teeth were being extracted [9,11,15,16]. As a consequence, there can be increased marginal bone loss in the spaces between neighboring teeth, a reduction in interdental bone height, and increased time necessary for the orthodontic space to close [16]. It sometimes becomes impossible to close the remaining spaces completely due to pronounced gingival invagination [7].…”
