“…From screening and eligibility, three available studies were reviewed and showed that counterclockwise and clockwise rotations of the MMC are stable outcomes immediately after surgery and at longest follow-up, with no statistically significant difference between treatment planning, mainly, when there is no preexisting temporomandibular joint pathology [12]. Both Class III patients had similar skeletal stability because the postoperative outcomes have remained stable regarding facial esthetic and occlusal functionality in a follow-up over 2 years.…”

“…Regardless of the malocclusion classification, prevalence or priority treatment, Class III patients can present different facials features that will be correlated with cephalometric aspects, one of them is the occlusal plane (OP) angulation [12]. The OP angle is defined as the angle formed by the Frankfort horizontal plane and the line tangent to the canine tips of the lower premolars and the buccal groove of the second molars.…”

“…The normal value for adults is 8° (±4°). DFD are often related to an abnormal OP angulation, and surgical alteration of this angle may have a substantial impact on the functional and esthetic outcomes for patients [12]. …”

“…The low OP facial type presents with the following characteristics: decreased OP angle; low mandibular plane angle; prominent mandibular gonial angles; strong chin relative to the mandibular dental alveolus; and Class I, Class II, or occasionally, Class III malocclusion. The HOP facial type presents with the following basic characteristics: increased OP angulation; anterior vertical maxillary hyperplasia and/or posterior vertical maxillary hypoplasia; anteroposterior mandibular hypoplasia; high mandibular plane angulation; and Class I, Class II, or Class III malocclusion with or without an anterior open bite [12]. …”

Dentofacial deformities (DFD) presenting mainly as Class III malocclusions that require orthognathic surgery as a part of definitive treatment. Class III patients can have obvious signs such as increasing the chin projection and chin throat length, nasolabial folds, reverse overjet, and lack of upper lip support. However, Class III patients can present different facial patterns depending on the angulation of occlusal plane (OP), and only bite correction does not always lead to the improvement of the facial esthetic. We described two Class III patients with different clinical features and inclination of OP and had undergone different treatment planning based on 6 clinical features: (I) facial type; (II) upper incisor display at rest; (III) dental and gingival display on smile; (IV) soft tissue support; (V) chin projection; and (VI) lower lip projection. These patients were submitted to orthognathic surgery with different treatment plannings: a clockwise rotation and counterclockwise rotation of OP according to their facial features. The clinical features and OP inclination helped to define treatment planning by clockwise and counterclockwise rotations of the maxillomandibular complex, and two patients undergone to bimaxillary orthognathic surgery showed harmonic outcomes and stables after 2 years of follow-up.

“…Concerns over CCWR of the OP still exist but ample research provides that such movements are stable. 11 CCWR is the normal pathway of growth of the maxilla and mandible. Patients with maxillomandibular growth restriction will likely be observed to have a steep occlusal plane and bimaxillary AP restriction.…”

Virtual three dimensional (3D) facial diagnosis and treatment planning has the potential to improve outcomes for orthognathic surgery patients. It is necessary to appreciate the inadequacies of traditional two dimensional treatment planning and how that may adversely affect the virtual 3D treatment planning process. Virtual 3D planning greatly improves the clinician's ability to diagnose and treat facial form and position problems that prevent the patient from accomplishing the three Functional Facial Keys (eating, breathing and communicating). It also enhances facial-skeletal orientation, maxillary and mandibular positioning, correction of asymmetries and occlusal plane management. This article presents a systematic approach to treat functional facial problems using virtual 3D treatment planning for consistent esthetic facial results. (Semin Orthod 2019; 25:230-247)
