Trauma oklusi dan penatalaksanaannya
P Pada keadaan khusus, gaya oklusal dapat menciderai jaringan periodontal danmengakibatkan perkembangan dari trauma oklusal. Trauma oklusal adalah suatulesi degeneratif yang berkembang saat kekuatan oklusal melebihi kemampuanadaptasi dari jaringan periodontal pendukung. Respon jaringan periodontalterhadap peningkatan gaya oklusal dibagi menjadi tiga tahap yakni yang pertama,kerusakan jaringan periodontal (injury) pada serat periodontal, nekrosis selfibroblas dan sel jaringan ikat, perubahan vaskularisasi, dan resorpsi tulangalveolar. Kedua, perbaikan kerusakan jaringan periodontal (repair) pada seljaringan ikat, serat periodontal, tulang dan sementum. Ketiga, adaptasipembentukan jaringan periodontal yang barn (remodeling) berupa penebalanligamen periodontal, kerusakan angular tulang alveolar tanpa terdapat poket, dangoyangnya gigi. Trauma oklusal dapat dikoreksi dengan koronoplasti untukmendapatkan oklusi yang harmonis.
I In special circumstances, occlusal forces can injure periodontal tissue andresulting in the development of occlusal trauma. Occlusal trauma is adegenerative lesion that develops when occlusal forces exceed capacityadaptation of the supporting periodontal tissue. Periodontal tissue responseThe increase in occlusal force is divided into three stages, namely the first,periodontal tissue damage (injury) to periodontal fibers, cell necrosisfibroblasts and connective tissue cells, changes in vascularization, and bone resorptionalveolar. Second, repair periodontal tissue damage (repair) in cellsconnective tissue, periodontal fibers, bone and cementum. Third, adaptationformation of new periodontal tissue (remodeling) in the form of thickeningperiodontal ligament, angular damage to the alveolar bone without pockets, andloose teeth. Occlusal trauma can be corrected with coronoplasty forachieve harmonious occlusion.
