SUMMARY

SUMMARY The. treatment of .patlents with dentofacial deformity involves the evaluation and treatment of many types of dental and skeletal problems. These problems require that all practitioners involved in patient care interact in a.multidlsclplinary team approach to treatm”ent.· This se quential. team approach yields the most satisfying results.

POSTSURGICAL TREATMENT PHASE

POSTSURGICAL TREATMENT PHASE C?mpletiCin of Orthodontics. When satisfactory range of jaw motion and stability of the osteotomy sites are achieved, the orthoctontic treatment can be finished. The heavy surgical arch wires are removed and replaced with light orthodontic wire. Final alignment and pcsitloning of the teeth is accomplished, as is closure of any residual extraction space. The light vertical elastics

DISTRACTION OF OEOGENESIS

DISTRACTION OF OEOGENESIS One nesv approach to correction of deficiencies in the mandible and the maxilla involves the use of distraction osteogenesis (DO). When correcting deformities associatcd with these deficiencies, the conventional osteotomy techniques have several potential limitations (described previously in this chapter). When large skeletal movements are required, the associatedsoft tissue often can

Combinatjon Deformities and Asymmetries

Combinatjon Deformities and Asymmetries Treatment may require a combination of maxillary and mandibular osteotomies to achieve the best possible occlusal, functional, and esthetic result (Figs. 25-27 and 25·28 on pages 590 through 593). Treatment of asymmetry in more than two planes frequently requires maxillary surgery, mandibular surgery, and inferior border osteotomies, as well as recontouring or augmentat

Maxillary and Midface Deficiency

Maxillary and Midface Deficiency Patients with maxillary deficiency commonly appearto have a retruded upper lip, deficiency of the paranasal and infraorbital rim areas, inadequate tooth exposure during smile, and a prominent chin relative to the middle third of the face.’ Maxillary deficiency may occur in the antero- Maxillary and Midface Deficiency Maxillary and Midface Deficiency is frequently seen.The

Maxillary Excess

Maxillary Excess Excessive growth of the maxilla may occur in the anteroposterior, vertical, or transverse dimensions. Surgical correction of dentofacial deformities with total maxillary surgery (i.e., Le Fort I) has only become popular since the early 197,Os. Before that time maxillary surgery was performed on a limited basis, and most techniques repositioned only portions of the maxilla with segmental surger

Mandibular Deficiency

Mandibular Deficiency The most obvious clinical feature of mandibular deficiency is the retruded position of the chin as viewed. from the profile aspect. Other facial features often associated with mandibular deficiency may include an excess labiomental fold with a procumbent appearance of the lower lip, abnormal posture of the upper lip, and poor throat form. Intraorally, mandibular deficiency is associated
