The Clinical Significance of Immediate Mandibular Lateral Translation: Critically Appraised Topic (CAT)

Summary
Recording immediate mandibular lateral translation (IMLT) in dental occlusion is not supported by evidence for clinical relevance. Current research lacks data on its prevalence and adverse events, questioning its necessity in restorative schemes.
Area of Science:
- Dental Science
- Occlusion Research
- Restorative Dentistry
Background:
- The clinical significance of immediate mandibular lateral translation (IMLT) in dental occlusion requires investigation.
- Assessing IMLT's role in occlusal rehabilitation is crucial for understanding its practical application.
Purpose of the Study:
- To critically appraise the clinical relevance of recording immediate mandibular lateral translation.
- To determine if IMLT measurement is a necessary component of occlusal analysis.
Main Methods:
- A comprehensive literature search was conducted using PICO, specific keywords (dental occlusion, immediate side shift, Bennett movement), and various study designs.
- Included 10 relevant English-language in vivo studies after eliminating duplicates and irrelevant articles.
Main Results:
- No evidence was found regarding the prevalence of IMLT in patients needing occlusal rehabilitation.
- The recording of IMLT is dependent on reference points and instruments, and its magnitude is minimal.
- No adverse clinical events are associated with omitting IMLT from restorative occlusal schemes.
Conclusions:
- The necessity of recording and reproducing immediate mandibular lateral translation on average patients and articulators is questionable.
- Current evidence does not support the routine inclusion of IMLT in restorative dental procedures.
