Abstract

Aim: To investigate the relationship between post orthognathic surgery changes in soft and hard tissue cephalometric variables in Class II and Class III patients and quality of life (QoL) measured using a condition-specific QoL questionnaire and to determine cephalometric predictors of the overall OQLQ after surgery.

Methods: The sample included 50 orthodontic patients, 28 Class II and 22 Class III skeletal relationships whose treatment included orthognathic surgery. Correlations between cephalometric changes and Orthognathic Quality of Life Questionnaire (OQLQ) were tested by Pearson’s correlation. Multiple linear regression was used to determine cephalometric predictors of the overall OQLQ after surgery.

Results: In Class II patients, OQLQ before surgery and changes in SNA were significant predictors for OQLQ after surgery. For Class III patients, OQLQ after surgery was significantly correlated with the change in mandibular plane angle and lower face height (r = 0.6 and r = 0.5 respectively). The decrease in facial angle was negatively correlated with OQLQ (r = -0.4). Mandibular plane angle, mandibular length, and OQLQ before surgery were significant predictors for OQLQ after surgery. 

Conclusion: QoL improved for Class II and III after orthognathic surgery. Changes in certain cephalometric measurements seem to predict quality of life after orthognathic surgery.

Abstract

Introduction: The effect of headgear on the space available for the eruption of upper third molars needed further investigation. Only a few studies looked at the after-treatment effect of headgear on that space, and none have evaluated the long-term effect after the average age of third molar eruption. Therefore, this retrospective study evaluated the short and long-term effects of cervical headgear on the space and eruption of the maxillary third molars and their long-term eruption status.

Materials and Methods: Records of Class II cases treated with cervical headgear were collected at the following time points: (T1) before treatment, (T2) after treatment, and (T3) taken at least 4 years after T2. An untreated control sample was collected from the Bolton-Brush study records. They were matched for age at each time point and malocclusion. Lateral cephalograms were used to measure the distance from the distal surface of the maxillary first molar (U6) to the pterygoid vertical plane (PTV). The third molar status at T3 was categorized into five groups: impacted, extracted, erupted, congenitally missing, and formation stage. Thirty-three cases were included in the cervical headgear group and 19 in the control group.

Results: The position of U6 changed significantly between the headgear and control group at T2 but was similar at T3. In the headgear group, the U6 was significantly distalized (3.3 ±2.9 mm) between T1 and T2 (P=0.006), however, there was a significant relapse of 5.9 (±4.6) mm between T2 and T3 (P<0.001). In the control group, the distance between U6 and PTV increased significantly from T1 to T2 (4.8 ±4.4mm) with minimal change from T2 to T3 (1.5 ±4.8mm). There was no significant relationship between headgear use and third molar status (p=0.108).

Conclusion: Headgear caused a temporary decrease in the U6-PTV distance that was recovered later. This decrease was not observed in the control group. Using cervical headgear to correct Class II malocclusion does not increase the risk of upper third molar impaction.
