Unit Three – OMS Procedures

Learning Outcomes

Explain common OMS procedures and select the dedicated armamentarium for each procedure


Assist in common OMS procedures as an integral part of the surgical team


Common Procedures

Extractions – the removal of teeth

  • single or multiple teeth
  • 4×8 – extraction of 4 third molars (wisdom teeth)

Orthodontic Interventions – surgeries designed to assist in orthodontic treatment (correction of malocclusions)

  • Bollard Plates – titanium plates that are temporarily screwed into the jaw; they provide anchorage for orthodontic movement
  • Exposures – surgical uncovering of a tooth in preparation for orthodontic treatment
  • Frenectomy – removal of tissue that prevents the normal position of teeth, tongue, (or prosthetic)
  • Luxate – surgical dislocation or displacement of a tooth from the alveolus to assist in eruption
  • Transplant – surgical removal of a tooth from one location to another

Biopsy – removal and examination of abnormal oral structures

  • Cysts and periapical lesions
  • Soft tissue lesions

Pre-Prosthetic Surgery – corrects abnormalities prior to prosthetic insertion (e.g. dentures and implants)

  • Soft tissue: removal or repair of fibrous, hyperplastic, and hypertrophic tissue
  • Alveolar ridge maintenance post-extraction: Allograft
  • Platelet Rich Fibrin (PRF) membrane:  Autograft
  • Collagen membranes: Allograft
  • Block bone grafts from patient’s donor site: Autograft
  • Bone grafts from patient’s donor site: Autograft
  • Sinus lift: with allograft or autograft, osteotome, or elevation
  • Tori Removal

Implantology – replacement of single tooth, multiple teeth, or full arches

  • First stage (initial placement): single, multiple, all-on four (full arch)
  • Second stage (typically 3-4 months post placement): assess for osseointegration, ISQ test, uncover

Orthognathic Surgery – corrects conditions of the jaw related to structure, growth, malocclusion or trauma

  • BSSO – Bilateral Sagital Split Osteotomy
  • Genioplasty – chin augmentation
  • Le Fort 1 – Maxillary Osteotomy
  • SARPE – Surgically Assisted Rapid Palatal Expansion

TMJ Surgery 

  • Arthrocentesis – TMJ arthrocentesis is a surgical treatment that involves irrigating the joint with the possibility of depositing a therapeutic drug
  • Eminectomy – A surgical reduction of the articular eminence of the TMJ

Emergency Surgery – emergent maintenance of circulation issues, pain, and infection

  • Cautery – coagulation of tissue by an electric surgical device
  • Debridement – removal of damaged tissue or foreign object from a wound
  • Facial Trauma – jaw wire
  • Incise and Drain (I & D) – clinical lancing
  • Oral-Antral Fistula – sinus exposure

It is always best to confer with your surgeon when choosing procedure specific protocols to prevent healthcare associated infections. Below are some examples:


Planning reduces errors in OMS. Creating procedure specific checklists will ensure the utmost in perioperative care, and in maintaining asepsis or sterility
