Do Mobility and Occlusal Trauma Impact Periodontal Longevity?

Area of Science:

• Periodontology
• Restorative Dentistry

Background:

• The relationship between tooth mobility, occlusal trauma (OT), and periodontal bone loss has been a long-standing debate in dentistry.
• Previous literature, primarily from the late 1990s, explored these connections, necessitating an update with more recent findings.

Purpose of the Study:

• To review and synthesize existing literature on the impact of tooth mobility and OT on periodontal health.
• To incorporate newer research from the 2000s to provide a contemporary understanding of these factors.
• To clarify the indications for occlusal therapy in the context of periodontal disease and tooth mobility.

Main Methods:

• Literature review of articles published in Dental Clinics of North America from the late 1990s.
• Inclusion of additional relevant studies from the 2000s to supplement the initial review.
• Synthesis of findings to evaluate the evidence linking mobility and OT to periodontal bone loss and tooth longevity.

Main Results:

• Limited strong evidence suggests that tooth mobility and OT significantly impact tooth longevity.
• Reducing inflammation in the periodontium is identified as a critical treatment component.
• Occlusal therapy is indicated when tooth mobility is progressive, comfort or function is compromised, or periodontal regeneration is planned.

Conclusions:

• While direct links between mobility/OT and tooth loss are not strongly supported by current evidence, managing periodontal inflammation is paramount.
• Occlusal adjustments and therapy should be considered strategically, particularly in cases of increasing mobility, functional deficits, or when advanced periodontal treatments are anticipated.
