Facial and occlusal esthetic improvements of an adult skeletal Class III malocclusion using surgical, orthodontic, and implant treatment

Evaluation of social appearance concerns and satisfaction after orthognathic surgery

The main aim of orthognathic surgery is to provide a good occlusion and masticatory function and to achieve positive changes in facial aesthetics. The aim of this study was to determine the reasons behind patients' acceptance of orthognathic surgery and their expectations from this treatment, to assess whether their expectations were met, the change in their self-confidence and their satisfaction, and finally, to use the results obtained to inform future surgical procedures to increase patient satisfaction. The study was designed as a cross-sectional observational study and included 73 people treated with orthognathic surgery (surgery group) and 42 people with minimal crowding who did not require treatment (control group). The study found that the primary reason for requesting orthognathic surgery was to improve facial appearance and that patients had high expectations in this regard. Using the Social Appearance Anxiety Questionnaire and the Expectation and Satisfaction Questionnaire, 73.97 % of patients in our study said the treatment met their expectations and 90.41 % said they were satisfied with the overall results of the surgery. The study also highlighted the importance of surgeon-patient communication and the satisfaction of the patient's environment with the final result in determining patient satisfaction. In conclusion, since patients' high expectations of orthognathic surgery influence treatment success and patient satisfaction, it is important to know and manage patients' expectations before treatment and to have good patient-surgeon communication to increase patient satisfaction after surgery.

Perception of Altered Smile Esthetics by Orthodontists, Dentists, and Laypeople in Riyadh, Saudi Arabia

Background

Mini-esthetics is an important concept in orthodontics concerned with relatedness of dentition to the face.

Purpose

We compared the perception of altered smile esthetics between orthodontists, dentists, and laypeople in Riyadh, Saudi Arabia.

Patients and Methods

A total of 216 participants (orthodontists, dentists, and laypeople) were conveniently surveyed. An image representing the ideal smile was altered in terms of buccal corridor, gingival display, and midline diastema. Using Likert scale, participants were asked to rate the attractiveness of the altered images.

Results

The three surveyed groups preferred wide rather than narrow buccal corridors. Also, as the amount of gingival display and midline diastema increased, the smile was rated less attractive. Age of participants was significantly associated with more precise recognition of gingival display and midline diastema, P<0.05 and P<0.001, respectively.

Conclusion

The concept of an ideal smile holds true across the heterogenous groups we studied despite gender and professional background.

Impact of orthognathic surgery on the treatment of gummy smile: an integrative review

The gingival smile is considered unpleasant and can be treated in different ways according to its etiological factor. When caused by maxillary vertical growth excess, orthognathic surgery may be indicated to correct the vertical excess. The aim of this integrative review was to evaluate the impact of orthognathic surgery on the treatment of gingival smile. An electronic search was performed of the PubMed/Medline, Cochrane Library, Scopus, and Google Scholar databases. The selection of studies was performed by two blinded reviewers. Firstly, studies were selected by reading the titles and the abstracts of articles. The references from each study selected were then searched to find articles that were not found in the electronic search. After reading the full-text articles, studies that met the inclusion criteria were selected. A total of 667 studies were identified, but only 19 were selected for the integrative review after applying the inclusion and exclusion criteria. The selected articles reported maxillary impaction from 2 to 10 mm, but this amount of superior repositioning of maxilla does not appear to be related to the initial gingival exposure described. Orthognathic surgery is not the first choice of treatment for gingival smile, but it appears to be a suitable therapy for other conditions in the same patient for improving a gummy smile by correction of gingival exposure.

3-Dimensional prediction of pre-surgical decompensation after atypical extractions and soft tissue simulation for ortho-surgical management of skeletal Class III malocclusion: A case report

Three dimensional imaging systems whether in the form of digital models, facial scanning or dolphin software play an important role in proper diagnosis and treatment planning of the orthosurgical cases. This case report highlights importance of three-dimensional treatment planning in the ortho-surgical management of the patient with skeletal Class III malocclusion involving atypical extraction. On clinical examination, patient had concave profile, prominent chin, deficient midface, flat cheekbone contour and prominent nasal projection. He had Class III molar and canine relation bilaterally with missing 12 (previously extracted), negative overbite and overjet with discordant maxillomandibular midlines. After 3-dimensional digital model set-up for occlusion planning and dolphin simulation for soft tissue prediction, extraction of left maxillary lateral incisor was planned followed by maxillary advancement and mandibular setback surgery and finish the occlusion in Class II molar relationship. After the orthodontic and orthognathic surgical treatment, the skeletal and dental imbalance was corrected, and most of the treatment objectives were achieved and patient was extremely satisfied with his facial profile. The treatment results were stable at the 3 years follow-up.
