OBJECTIVE: To determine if there was a basis for the treatment of temporomandibular disease (TMD) using the chiropractic protocol developed by Activator Methods, International. SETTING: Private, solo practice of an Activator advanced proficiency rated chiropractor with 15 years experience. DESIGN: Prospective case series. PARTICIPANTS: Nine adult volunteers with articular TMD recruited from the practice of the treating clinician. Main outcome measures Change from baseline to follow-up of Visual Analog Scale (VAS) for temporomandibular joint (TMJ) pain and maximum active mouth opening without pain. INTERVENTIONS: Full spine and TMJ adjusting in accordance with the advanced protocol of Activator Methods, International. Participants were typically seen 3 times per week for 2 weeks and according to individual progress thereafter for 6 more weeks. RESULTS: Eight participants completed outcome assessments. The median VAS decrease was 45 mm (range 21-71); all experienced improvement. The median increase of mouth opening was 9 mm (range 1-15); all showed improvement. CONCLUSION: The results of this prospective case series indicated that the TMD symptoms of these participants improved following a course of treatment using the Activator Methods, International protocol. Consequently, further investigation of this type of chiropractic treatment for patients with the articular type of TMD is warranted.

OBJECTIVES: To test the hypothesis that there are no gender differences in the outcomes of patients with class II malocclusion treated with the headgear-activator Teuscher appliance (HATA). DESIGN: Retrospective, longitudinal SETTING AND SAMPLE POPULATION: Puerto Rico and Scotland, UK. Thirty-one patients requiring correction of class II division 1 malocclusions. EXPERIMENTAL VARIABLE: Male and female patients treated using HATA. OUTCOME MEASURES: Mean pre- and post-treatment parameters derived from cephalometry subjected to t-tests, and finite-element scaling analysis (FESA), which localizes and quantifies differences between mean pre- and post-treatment configurations. RESULTS: Post-treatment, cephalometry showed that for both males and females, angle SNA decreased, SNB increased, and lower facial heights increased significantly (p < 0.01). For the female post-treatment configuration, FESA revealed large size increases (approximately 20%) located in the inter-maxillary region, the ramus and mandibular body, and around the nasal and mental regions. Conversely, the lip region was diminished (approximately 20%). Similarly, male post-treatment showed size increases located in the inter-maxillary region that extended into the nasal region and the mandibular body (approximately 10-15%), and around the chin (15%). The lip region was diminished (approximately 5%). CONCLUSION: In the attainment of a normal occlusion, both male and female patients treated for class II malocclusions using HATA exhibit antero-posterior restraint of the maxilla, improvements in the mandible maintaining facial height, and lip changes commensurate with improvements in the soft tissue profile.
