Diş implantı uygulamalarında ultrasonik titreşim destekli delme yöntemlerinin incelenmesi: kuvvet ve ısıl etkilerin azaltılmasına yönelik karşılaştırmalı bir analiz

Dental implantology demands precise control over mechanical and thermal loads during osteotomy to ensure successful osseointegration and implant longevity. Conventional Drilling (CD) techniques are often associated with elevated thrust forces and excessive heat generation, both of which can lead to microdamage and thermal necrosis in bone tissue. Ultrasonic-Assisted Drilling (UAD), incorporating high-frequency vibrations into the cutting motion, offers a promising alternative. This study presents a coupled thermo-mechanical finite element (FEM) model, experimentally validated, to compare the performance of UAD and CD. Results show that UAD reduces thrust force by 30–35% and peak temperature by 25–30%, maintaining values below the critical 47°C threshold for bone viability. A sensitivity analysis on rotational speed, vibration amplitude, and frequency highlights their individual and combined effects on thermal and mechanical performance. Furthermore, a response surface model (RSM) was constructed to optimize these parameters for minimal force and temperature. These findings confirm that UAD significantly reduces both mechanical and thermal risks, providing evidence-based parameter guidelines to enhance safety and efficiency in dental drilling applications.
