Efficiency Comparison of Proximal Contact Adjustment Methods: Traditional Stone vs. Diamond Strip in Dental Restorations

Objectives: This study aimed to compare the efficiency of two proximal contact adjustment methods in dental restorations: the traditional stone method and the recently introduced diamond strip method. Proper proximal contact force is crucial for maintaining the integrity of the dental arch and protecting teeth and supporting tissues. Traditional methods for adjusting contact strength, such as stones or silicon, depend on the clinician's proficiency and may not provide consistent results. The recently introduced diamond strip method offers a more accurate and efficient alternative.
Methods: The proper contact force was first determined by measuring the proximal contact strength of clinical crowns in an anonymous patient (n=40) adjusted chairside with the dental floss snap technique. The study involved crown specimens divided into 8 groups based on adjustment method, prosthetic material (Zirconia, Feldspathic porcelain), and clinician (A or B). The duration and number of adjustments required to achieve the proper contact force were investigated.
Results: The results demonstrated that the diamond strip method significantly reduced the time required for adjusting the contact strength compared to the stone method, regardless of the prosthetic material and clinician. Furthermore, the diamond strip method required fewer adjustments, suggesting a more accurate and efficient adjustment process. No significant difference was observed in time consumption among the prosthetic materials within the same adjustment method.
Conclusions: The diamond strip method proved to be a more efficient and consistent method for adjusting proximal contact strength in dental restorations compared to the traditional stone method. The method not only reduces the time required for adjustments but also provides more predictable contact strength reduction per adjustment. Dental practitioners may benefit from adopting the diamond strip method for adjusting proximal contact strength, ensuring the proper contact force is achieved in a more efficient and consistent manner.
