“…Patients with malocclusion are affected predominantly and have been investigated in several studies [4][5][6]. Orthognathic patients with class II and III malocclusion showed major variations of the temporomandibular joint (TMJ) in size and shape [4,7].…”

Purpose This study was conducted to elucidate volumetric data of mandibular condyles of orthognathic patients by analyzing cone beam computed tomography images based upon semiautomatic segmentation. Methods Cone beam computed tomography images of 87 patients with malocclusions were analyzed in this retrospective study. Patients were between 17 and 53 years old and diagnosed with Angle class I, II, or III malocclusion. By using the validated open-source software “ITK-SNAP,” the volumetric measurements of 174 mandibular condyles were performed. Volumetric analysis was performed according to intra-subject side differences by paired Student t test. In accordance to inter-subject side, gender, age and type of malocclusion differences bivariate analysis and ANOVA were applied. Results The mean volume for the right condyle was 1.378 ± 0.447 cm3, with a maximum of 2.379 cm3 and a minimum of 0.121 cm3. The mean volume for the left side was 1.435 ± 0.474 cm3, with a maximum of 3.264 cm3 and a minimum of 0.109 cm3. Bivariate analysis indicated a highly significant inter-subject difference between the volume of the left and right mandibular condyles (p < 0.01). Females had a significantly smaller condyle volume than males (p < 0.05 left condyle; p < 0.01 right condyle). Conclusion The fact that shape and volume of mandibular condyles show a high susceptibility to pathological alterations and particularly malocclusions makes a precise knowledge about volumetric changes indispensable. Our results show that significant inter-subject differences in condyle volume could be found with respect to the side and gender. Larger volumes could be assessed for the left condyle and for male patients.

“…As a multidisciplinary approach is often necessary to achieve esthetic harmony between face, teeth, lips and gums, interaction with various specialties of Dentistry must be used to solve the complexity of each patient's case [ 13 ]. Considering that a harmonious smile is influenced by several factors such as minimal gingival exposure, presence of healthy gingival tissue in interproximal spaces, symmetry between the upper gingival margin and upper lip, harmony between anterior and posterior segments, and correct proportions and anatomy [ 14 ], this case also involved a stage of gingival repair and tooth whitening, important steps in the search for an excellent result.…”

Introduction and importance Orthognathic surgery aims to restore the functional and esthetic standards of the face and non-surgical or minimally invasive procedures have been optimizing the results of facial orthosurgical treatments. This case report aimed to show the use of minimally invasive techniques that, associated with orthognathic surgery, represent a trend in current oral and maxillofacial rehabilitation. Case presentation A female patient, 28 years old, white, sought care from the Dentistry team of the São Vicente de Paulo Hospital, in Passo Fundo, Brazil, complaining of mandibular prognathism, anteroposterior maxillary deficiency, dental crowding, malocclusion, functional and esthetic changes that negatively affected her psychosocial interactions and stomatognathic function. The treatment involved orthodontics, orthognathic surgery, and orofacial harmonization with dermal fillers. Clinical discussion The multidisciplinarity among the specialties of Oral and Maxillofacial Surgery and Traumatology, Orthodontics, and Orofacial Harmonization add and contribute to the process of planning and implementing the treatment proposed, as well as the prognosis toward patient satisfaction. Conclusion The surgical procedure associated with minimally invasive facial harmonization not only corrected the functional complaint of the patient but also played an important role in improving facial harmony, contributing significantly to self-esteem.

“…44 It was first presented in 1972, published in the plastic surgery field by Rubinstein and Kostianovsky, 18,25 and introduced years later in the dental cosmetic area by Rosenblat and Simon. 36 This procedure has been suggested for patients requesting a less invasive procedure compared with orthognathic surgery 16,17 and has evolved significantly over the years.…”

“…4 However, most patients refuse this surgery due to its high morbidity and the need to be hospitalized. 16,17 The lip repositioning technique (LRT) described for the first time in plastic surgery by Rubinstein and Kostianovsky, 18 is a widely used, effective, safe, and predictable treatment with an average GS reduction of 2.71 mm. 19,20 The LRT alone could be used when the patient presents a short upper lip, HUL (lip mobility > 8 mm), and VME except for severe cases.…”

The lip repositioning technique (LRT) is considered a safe and predictable gummy smile (GS) treatment. However, since Rubinstein and Kostianovsky introduced it in 1973, it has undergone several modifications. This article aims to review and provide a historical compilation of LRT evolution to help clinicians understand each technique's description and the rationale for its modifications to treat GS.An electronic search was performed in Medline, Scopus, and Cochrane Library up to May 2021 including the terms “lip repositioning,” “lip repositioning technique,” or “lip repositioning surgery” and studies evaluating or discussing the original LRT's modifications in detail. The search had no language or time restrictions. Additionally, a hand-searching of references of all included articles was performed.Modifications described in the literature include muscle severance, subperiosteal dissection of the gingiva, frenectomies, and the use of adjuvant products. They aim to minimize relapse, morbidity, and improve stability. Discomfort, scar formation, and pain were the most frequent complications reported. The choice to use a modification should be analyzed and customized to the individual patient's needs.
