lec 7 - preprosthetic surgery Flashcards
What are the 2 indications of simple alveoloplasty?
- Multiple teeth extraction
- Prosthetic preparation
Refers to the surgical reshaping or smoothing of the bony structures in the jaw, specifically the alveolar ridges. This is performed at the SAME TIME as extraction of multiple teeth.
Recontouring of Residual Ridges / Simple Alveoloplasty
This is a specific surgical technique used to reshape and reduce the height of alveolar ridges by removing interdental bone (septum) while preserving the external cortical plates. This is done to reduce undercuts or excessive bony prominences, removing bone from within the ridge and maintaining soft tissue support.
Intraseptal alveoloplasty
Common indications of intraseptal alveoloplasty (4)
- Ridge undercuts
- Soft tissue preservation
- Shallow vestibule
- Minimal bony resorption
This is a conservative surgical approach that reshapes alveolar ridge while preserving the external contour. It is ideal for managing bony undercuts and improving soft tissue contours without significantly reducing ridge height.
Intraseptal alveoloplasty
This is a surgical procedure that involves the removal or reshaping of excess bone and sometimes soft tissue from the maxillary tuberosity. This is performed when the enlarged tuberosity interferes with prosthodontic rehabilitation.
Maxillary tuberosity reduction (hard tissue)
Indications for maxillary tuberosity reduction (4)?
- Prosthetic interference
- Limited interarch space
- Bony prominence/irregularity
- Implant placement preparation
Possible complications for maxillary tuberosity reduction
- Sinus perforation
- Excessive bleeding
- Infection
Refers to bony growths on the outer (buccal) side of the upper and lower jaw that can interfere with placement of dentures.
Buccal exostosis
Surgical correction of buccal exostosis where excess bone is surgically removed to smooth the ridge.
Exostectomy
These are bony outgrowths along the sides of the palate (roof of the mouth). They can hinder the placement of upper dentures and may cause discomfort.
Lateral palatal exostosis
This is a bony ridge located on the inner aspect of the mandible (lower jaw). This ridge can be excessively pronounced leading to discomfort when wearing lower dentures.
Mylohyoid ridge (reduction)
A common preprosthetic surgical procedure to remove bony growths that can interfere with placement of denture.
Tori removal
Bony growths that develop along the midline of the hard palate.
Torus palatinus
Bony growths that form along the inside of the lower jaw, typically near the premolars and above the mylohyoid ridge. They are often bilateral and benign.
Torus mandibularis
Also known as Epulis fissuratum or Denture fibrosis
Inflammatory fibrous hyperplasia
This is a benign overgrowth of fibrous tissue in response to chronic irritation, most commonly caused by ill-fitting dentures.
Inflammatory fibrous hyperplasia
This procedure removes or modifies the small fold of tissue that connects the inside of the upper and lower lip to the gums.
Labial frenectomy
Indications for labial frenectomy (4)
- Diastema
- Denture fit issues
- Speech and feeding problems (in children)
- Gum recession
This procedure releases or removes the small fold of tissue that connects the underside of the tongue to the floor of the mouth to improve tongue mobility.
Lingual frenectomy
A condition wherein the lingual frenum is too short or right, causing breastfeeding problems, speech difficulty, oral hygiene issues, and restricted tongue movement.
Ankyloglossia / tongue-tie
Also known as socket preservation
Alveolar ridge preservation
A procedure performed after tooth extraction to minimize bone loss and preserve the natural shape and height of the alveolar ridge.
Alveolar ridge preservation (ARP) / Socket preservation
Bone from the patient’s own body
Autograft
Bone from donor
Allograft
Bone from another species such as bovine
Xenograft
This applies a uniform pressure over the graft to enhance contact between the graft and the recipient base.
Bolster stitches
Refer to surgical procedures involved in placing a type of removable prosthetic denture that is supported by natural teeth or dental implants.
Overdenture surgery
These overdentures are supported by remaining natural teeth that have been modified to allow for better fit and function.
Tooth-supported overdenture
These overdentures rely on dental implants embedded in the jawbone.
Implant-supported overdenture
