DENTURE FRACTURE & REPAIR
Technically Dentures can fracture in one of two ways:
By IMPACT where one hard blow results in instant breakage
By FATIGUE when the denture base is subjected to repeated stresses.
An impact fracture is usually caused by patient carelessness or accident.
May be associated with
(1) The design of the denture
(2) Oral anatomy of the patient.
(3) Its use or abuse by the patient.
(4) Factors introduced in the laboratory.
(5) Previous repairs.
A "U" shaped denture designed
A large diastema between the anterior teeth
This denture has become bleached and very thin with long-term cleaning and wear.
Non-flanged or “open-faced” denture
|As a result of prolonged use of abrasive cleaners and vigorous brushing over many years acrylic resin will wear very thin and therefore become very prone to fatigue.|
