Abstract:

Dentofacial deformities accompanied by dental defects significantly impair the fundamental physiological functions of affected individuals，including chewing，articulation，and respiration.Additionally，these conditions detrimentally affect facial aesthetics，leading to diminished self-esteem and profound implications for psychological well-being and overall quality of life.The primary etiological factors contributing to dentofacial malformations associated with dental defects include congenital tooth agenesis， severe maxillofacial trauma，periodontitis， and dental caries.Given that dentofacial anomalies involve intricate anatomical structures such as the jaws，teeth，soft tissues，and nervous system，the existence of dental defects further complicates the clinical scenario.Conventional treatment strategies，which are often limited to single-specialty or simplistic combined orthodontic-orthognathic approaches，frequently fail to adequately restore the functional and aesthetic aspects of the affected patients.The diagnosis and management of dentofacial anomalies with dental defects typically necessitate a comprehensive and systematic multidisciplinary approach，incorporating expertise from oral and maxillofacial surgery， prosthodontics， orthodontics，implantology，periodontics，endodontics，and other relevant disciplines.By leveraging multidisciplinary collaboration，treatment duration can be significantly reduced， while enhancing the aesthetic outcomes and masticatory function of patients in a timely manner，thus achieving optimal treatment results.
