Soft-tissue changes associated with different surgical procedures for treating class III patients

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of upper removable appliances on the hard and soft tissue structures in subjects with postural Class III. Methods: The material consisted of cephalometric films of 17 Class III patients (8 females and 9 males, with a mean age of 10.10 ± 1.63). Each treated patient was matched before treatment with Class III subject for sex and age. Differences in treated group at T1 and T2 and between treated and untreated groups were examined using paired t-test and independent t-test respectively. Results: Treated and untreated Class III subjects differed in mandibular prognathism (SNB, P<0.01). Upper incisors proclined and inter-incisal angle reduced during treatment (P<0.001). Soft tissue A point moved anteriorly as maxillary incisors were proclined (P<0.05). Soft tissue profile was improved (NNP, P<0.05; NAP, P<0.01). Conclusion: Skeletal, dental and soft tissue changes were found in patients treated by upper removable appliance in postural Class III patients. Clinical relevance: upper removable appliance is an efficient method to procline upper incisors in postural Class III malocclusion and may be of greater influence in improving soft tissue profile.

Cephalometric Study

Objective: This longitudinal retrospective cephalometric study was undertaken in an attempt to evaluate the effect of Class III activator on the soft tissue structures in subjects with skeletal Class III. Methods: The material consisted of cephalometric films of 26 Class III patients (13females and 13 males, with a mean age of 13.58±4.38 years). Each treated patient was matched before treatment with Class III subject for sex and age. Differences at T1 and T2 were examined using paired t-test. Results: After treatment the patients' soft tissue profile improved significantly compare with before treatment. Conclusion: Soft tissue changes were found in patients treated by Class III activator in skeletal Class III patients. Clinical relevance: Class III activator may be an efficient method to improving soft tissue facial profile in Skeletal Class III malocclusion.

Le Fort I

Bac kground:The principlegoal of orthognathic surgery is to establish a balanced and stable dento-skeleto facial complex. This mandates the surgeon and the orthodontist to be able to predict the soft tissue changes to the orthognathic surgery precisely, which is accurately possible using 3-D imaging. Aims: To evaluate the soft tissue changes following class III orthognathic surgery using 3-D imaging. Settings and Design: Systematic review. Methods and Material:This review was conducted according to Preferred Reporting Items for Systematic Reviews and meta-Analyses guidelines systematically searching the six databases including PubMed, Cochrane, Google Scholar, LILACS, Directory of Open Access Journals, and OpenGrey. Statistical analysis used:Not applicable. Results: This systematic review comprises of most UpTo Date evidence from eleven articles answering the review questions. Conclusion: Le Fort I advancement shows significant increase in the alar width, alar cinch, upper lip, chelion, labiale superius, crista philtri, pronasale and subnasale. Mandibular setback shows significant backward movement of soft tissue point B, labialeinferius and subnasale and chin.
