According to the principles laid out by Ash and Ramfjord, an occlusion is considered functional and stable when it meets specific biological criteria rather than matching a rigid geometric ideal. These criteria include:

Ash and Ramfjord emphasized that . Instead, pocket formation requires bacterial plaque. However, when plaque-induced periodontitis and progressive occlusal trauma coexist, the destruction of alveolar bone accelerates drastically. Clinical Interventions and Therapies
A central tenet of the text is the role of (premature contacts) in the development of TMDs. The text explains how abnormal occlusion can lead to muscle splinting, pain, and dysfunction. 3. Occlusal Adjustment (Occlusal Equilibration)
While modern dental medicine has integrated digital dentistry, intraoral scanning, and advanced computerized gnathology (like T-Scan analysis), the biological principles laid out by Ash and Ramfjord remain unchanged. Understanding the neuromuscular control of the jaw and the physiology of mastication is still essential for success in: However, due to copyright restrictions, full‑text PDFs are
