SEM AND IN VIVO STUDY OF ADHESION CHARACTERISTICS OF TITANIUM AND POLYTETRAFLUOROETHYLENE SURFACES HEALING SCREWS

BULLETIN OF STOMATOLOGY AND MAXILLOFACIAL SURGERY, Год журнала: 2024, Номер unknown, С. 45 - 55

Опубликована: Май 18, 2024

Background: The long-term maintenance of implants and the prostheses they support depends on many factors. Specifically, patient's biotype is important where presence a significant thickness keratinized gingiva should ensure real biological seal, whose formation also influenced by healing screw. screws normally used are made titanium; however, their cost induces dentist to use them for improper single use. possibility using materials other than titanium such as polytetrafluoroethylene (PTFE) construction can therefore be advantageous. Objectives: aim this experimental clinical study test new PTFE exploiting chemical-physical characteristics undoubted economic advantages. Materials methods: 10 patients were taken into consideration 2 inserted in each. In each patient second phase, screw inserted. After 7 days, removed allow analysis under an electron microscope. Results: SEM showed that surface has ability accumulate much less organic material control screws. Furthermore, have been shown reduce level inflammation induced reuse compared traditional Conclusions: reduced screw, together with intrinsic material, represent promising characteristics, which make advantageous practice.

Dental implants have been used as an effective treatment for missing teeth. implantology has a long history that reaches back to ancient times when attempts were made replace teeth with various materials. Modern dental are designed osseointegrate, where the implant fixture fuses jawbone. The surgical procedure involves placing implant, followed by adaptation of surrounding tissue. There two main techniques: one-stage surgery and two-stage surgery. One-stage allowing healing abutment protrude through gums. This eliminates need second but carries risk overloading during phase. Two-stage is standard approach, initially submerged, performed connect abutment. choice between depends on many factors, including bone quality, clinical parameters, aesthetic considerations. offers quick aesthetics can pose higher failure due early loading. provides success rate requires procedures.
