A Clinical Study on the Gingival Regeneration with Reference to the Curative Process

Abstract

In 1962 the authors published their study as “303 Clinical Cases of the Gingival Regeneration in Periodontal Diseases” (The Journal of Nihon University School of Dentistry, Vol. 5, No. 2).The feature of our technic described in that study is to excise in a fairly wide area the region periodontally afflicted and expose an alveolar bone about 3-4mm by removing the alveolar mucosa and apply a surgical pack directly on the exposed alveolar bone after having cleaned the deposit and imperfect gingiva and, if necessary, osteoplasty is administered. In that study, we stated to the effect that the advantage of this technic consists in the redction of operational time since it does not require suturing as in the case of flap operation and the good postoperational growth of interdental papilla. As distinct from any previous gingival restoraion or curettage technic, a cure under this technic can be effected by means of entirely new gingiva, not from the old native gingiva. A brief summary of the technic together with illustrations appeared in the Dental Abstracts, American Dental Association (Vol.9, No.2, pp. 111-112, 1962). Since this study was published, we have further aplied the same technic to more patients amounting to over 1000 at the time of writing.Based o these numerous clinical cases, we here report on their curative process by means of roentgenographical findings and magnified photographs to illustrate the manner of curative process in the light of histology.
