title: Comparison Between Physics and Conventional Forceps in Simple Dental Extraction.
abstract: BACKGROUND
  Atraumatic dental extraction preserves bone, gingival architecture, and allows for the option of future or immediate dental implant placement. A number of tools and techniques have been proposed for minimally invasive tooth removal such as physics forceps. The biomechanical design of physics forceps decreases the incidence of root fracture, and maintains the buccal bone plate, which is essential for the proper healing of an immediately placed dental implant.
  
  
  OBJECTIVE
  This study was conducted to evaluate the efficacy of physics forceps versus conventional forceps in simple dental extraction.
  
  
  METHODS
  200 adult patients seeking simple dental extraction were selected from the Outpatient Clinic in the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University, Egypt. The selected patients were randomly allocated into two groups: group I: included 100 patients, in this group extraction was done using physics forceps, and group II: included 100 patients, in this group extraction was done using conventional forceps.
  
  
  RESULTS
  In physics forceps group: crown fracture occurred in three cases (3 %), buccal bone fracture occurred in three cases (3 %), and root fracture occurred in 14 roots (8.5 %), while in conventional forceps group: crown fracture occurred in 10 cases (10 %), buccal bone fracture occurred in seven cases (7 %), and root fracture occurred in 27 roots (16.6 %).
  
  
  CONCLUSIONS
  Physics forceps are innovative extraction instruments. By using them, it is possible to perform difficult extractions, with predictable results, and without need to reflect a flap. Using physics forceps decreases the incidence of crown, root, and buccal bone plate fractures, in comparison to the conventional forceps.
