[Preliminary study on tactile function of implant-supported single crowns]

Area of Science:

• Dental Implantology
• Biomaterials Science
• Sensory Neuroscience

Context:

• Assessing tactile sensitivity is crucial for functional restoration with implant-supported single crowns (ISSC).
• Understanding variations in tactile perception can inform clinical adjustments and patient expectations.
• Previous research has not comprehensively evaluated tactile thresholds across multiple orientations and demographic factors in ISSC.

Purpose:

• To quantify the passive tactile threshold of implant-supported single crowns (ISSC) in six orthogonal directions.
• To identify factors impacting tactile perception in ISSC.
• To provide data for personalized occlusal adjustments in implant restorations.

Summary:

• Passive tactile thresholds were measured for 24 ISSC in various orientations and compared to natural teeth.
• Significant differences were found based on orientation, location (maxillary anterior vs. posterior), and patient sex.
• No significant difference was observed between maxillary and mandibular posterior teeth or over a one-month period.

Impact:

• ISSC demonstrated a passive tactile threshold over 65 times higher than natural teeth, indicating altered sensory feedback.
• Findings highlight the need for individualized occlusal adjustments considering orientation, tooth position, and patient demographics.
• This research contributes to optimizing functional outcomes and patient satisfaction with dental implant restorations.
