Application of a systematic protocol in the treatment of TMDs with occlusal appliances: effectiveness and efficiency in a longitudinal retrospective study with medium-term follow-up

OBJECTIVE: This study aimed to assess effectiveness, efficiency, and feasibility of a systematic protocol for the choice and management of occlusal splints (OA) in the treatment of temporomandibular disorders (TMDs). MATERIALS AND METHODS: A longitudinal retrospective study was conducted. Two different samples, G1 + G2 (337 patients), between January 2011 and January 2014, were selected according to inclusion and exclusion criteria. G1 was composed of patients visited at Policlinico Umberto I, Head-Neck Department, Sapienza University of Rome, Italy, and patients in G2 visited at a private structure in Rome. Pain records and functionality were compared before (T0) and at the end of therapy (T1). A follow-up group, composed of 100 patients randomly selected among those who completed treatment for at least 1 year (T2), was analyzed and symptomatology records were compared. Descriptive statistical analysis was performed. RESULTS: In the entire sample, joint and muscular pain, joint noises and mandibular functionality, headache, and neck pain improved from T0 to T2. The average time for articular and muscular recovery was 6.4 months. Comparing treatment outcomes, there were not statistically significant differences between the two groups. CONCLUSIONS: Treatment outcomes using this setting of protocol showed a positive trend also in the medium term. The use of a systematic protocol seems to reduce operator-dependent factors.
