Purpose: The article reviewed the various studies on semiadjustable articulators (SAA) to determine their uses, accuracy and limitations in orienting the cast. Materials and methods: An electronic and manual search of PubMed and Medline databases and other published articles was performed. The article concomitant to question in focus on accuracy of cast orientation on to the SAA with the help of facebow when compared to the lateral cephalogram was included. Other question in focus was whether interocclusal records used for programming the articulator are more accurate than the computerized jaw-tracking devices. Article on reliability, repeatability and interchangeability of SAA were also included. The study also focused on the use of SAA in various specialties of dentistry with the help of available literatures. Only articles in English were considered for the study. Results: The initial search resulted in 450 papers. The reviewers independently screened the abstracts for those articles related to the focus question. Of the resulted 72 studies, 16 were excluded for not being in English, resulting in 56 entries. Hand-searching yielded 2 additional papers. Conclusion: SAA seems reliable in interchangeability and promising to be used in various fields of dentistry. The condylar guidance obtained by SAA proves to be more accurate than other radiographic methods. Jaw motion analyzer is more accurate in adjusting the SAA rather than protrusive records.
