“…[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] The indication for molar intrusion is often based on the assumption that the value of molar height in open bite patients is greater than in the ''normal population.'' 2,6,10,[27][28][29] Many authors state that increased molar height is one of the common features of individuals with dentoskeletal open bite, and they advocate molar intrusion to correct the disharmony. [12][13][14][15][16][17][18][19][20][21]30,31 However, other authors do not support these claims.…”

“…In growing patients, relative intrusion of the molars is recommended to control for vertical development of the jaws. 1 In adult patients, absolute intrusion of posterior occlusal segments can be performed with the aid of temporary anchorage devices, [2][3][4][5][6][7][8][9][10] and surgical treatment can be considered as well. The choice of treatment protocol depends on many factors, including esthetic and occlusal aspects, morphologic characteristics, and the severity of the skeletal anomaly.…”

Objective: To evaluate the skeletal and dentoalveolar components in adult subjects with skeletal open bite in the presence or absence of dental compensation. Materials and Methods: The study sample included 69 adult female subjects who belonged to three groups according to skeletal vertical relationships and overbite. A total of 15 variables (5 angular, 10 linear) were evaluated. Values in the dentally compensated open bite group (COBG), the dentally noncompensated open bite group (NCOBG), and the control group with normal vertical skeletal relationships and overbite (CG) were compared by means of parametric statistics. Results: The COBG and the NCOBG showed significantly greater incisor and molar heights in both jaws than the CG. No significant difference in upper or lower molar height was found between COBG and NCOBG. Incisor height was significantly greater in COBG than in NCOBG. Elongation in the incisor region was accompanied by significant narrowing of the lower anterior alveolar process in both skeletal open bite groups. Proclination of the upper incisors was significantly smaller in the COBG than in the other groups. Conclusions: Dentoalveolar components consisting of incisor elongation and inclination play a significant role in compensating for skeletal open bite configuration in adult subjects. Increased molar height is a common finding in adults with skeletal open bite. (Angle Orthod. 2011;81:564-569.)

“…In open bite treatment, molar intrusion or incisor extrusion is needed to correct the occlusal plane of the upper and lower arches 23,24,34 because a discrepancy in tooth height between the anterior and posterior teeth generally exists. The treatment of open bite by incisor extrusion has been reported to result in a gummy smile.…”

“…19 Recently, a new treatment method for anterior open bite with skeletal Class I and II that employs molar intrusion via anchorage with an implant such as a titanium screw has been reported. 3,[20][21][22][23][24] Intrusion of the molars enables autorotation of the mandible in a closing direction, thus closing the anterior open bite and reducing anterior facial height. 25 If intrusion of the molars with titanium screws and bilateral sagittal split osteotomy (BSSO) are performed instead of two-jaw surgery in patients with skeletal Class III and open bite, the surgical invasion is reduced and changes in the nasal profile can be avoided.…”

Skeletal Class III and open bite treated with bilateral sagittal split osteotomy and molar intrusion using titanium screws

Two-jaw surgery has been performed for the treatment of severe skeletal open bite cases to obtain stability of occlusion after treatment. If molar intrusion with titanium screws could be performed instead of surgical superior repositioning of the maxilla, the incidence of surgical invasion would be reduced. However, there have been few reports of such a therapy. This case report describes treatment for skeletal Class III and open bite with bilateral sagittal split osteotomy and intrusion of the molars using titanium screws. The patient had a concave profile, a long lower facial height, Class III malocclusion, and excessive anterior open bite following mandibular protrusion and a high mandibular plane angle. The mandible autorotated closed 3.5u following intrusion of the upper and lower molars using titanium screws during the presurgical orthodontic treatment phase. After the autorotation of the mandible, a mandibular setback with a bilateral sagittal split osteotomy was performed. The posttreatment records showed a good facial profile and occlusion. The mandible was stable 1 year after surgery. These results demonstrate that surgical orthodontic treatment combined with bilateral sagittal split osteotomy and intrusion of the molars using titanium screws can reduce the need for surgical invasion by avoidance of maxillary surgery and was effective for correcting the facial profile and occlusion in a skeletal Class III and open bite patient.

“…The list of comparative studies 7,21,30,39,44 , experimental studies 26,45,51 , some randomized clinical trials 7,35,38,71 and systematic reviews 14,16,20,22,43 has continued to grow over the years. This can be seen as evidence for an ongoing therapeutic revolution that is impacting all aspects of orthodontics and that is suggesting new solutions for the buccal technique 8,15,28,34,36,46,55 as well as for lingual orthodontics 4,29,37,41,69 , for the aligner technique 11,73 or for orthopaedics 13 .…”

Over the past decade, the interest for miniscrews is continuously growing as confirmed by the amount of recent published studies. In particular, their use allows to make corrections in a single phase and avoids extractions of premolars, while keeping usual goals of treatment. Main results of pilot studies and some clinical examples are presented here to illustrate our therapeutic approach for the treatment of tooth discrepancy in Class I, Class II and Class III situations.
