Causes of Injury in Fixed Partial Denture Tooth Preparation
Causes of Injury in Tooth Prep
Temperature
Considerable heat is generated by friction between a rotary instrument and the surface being prepared. Excessive pressure, higher rotational speeds, and the type, shape and condition of cutting instrument. Feather light touch and water spray should be used.
Chemical Action
The chemical action of some dental materials (bases, restorative resins, solvents and luting agents) can caused pulpal damage.
Bacterial Action
Pulpal damage under restorations has been attributed to bacteria that either were left behind or gained access to the dentin because of microleakage. Antimicrobial agent after tooth preparation and before cementation should be used.
Adjusting a Removable Partial Denture Metal Framework
There should be no clicking sound when a Removable Partial Denture metal framework is being seated inside the patient’s mouth. Clicking sound is a sign of excessive force applied on the abutments. The clasps should engage the abutments passively. There should be no pressure or force to the abutments especially when there’s no dislodging forces applied to the Removable Partial Denture. Below is a simple procedure to adjust a casted upper Removable Partial Denture framework.
Correction fluid is used to check pressure points or areas on the framework.

Remove only minimal tooth structure. Overenlargement can perforate or weaken the root. The thickness of the remaining dentin is the prime variable in fracture resistance of the root.
Coronal
As much of the coronal tooth structure should be conserved as possible.

Removable Partial Denture with Metal Framework
Cobalt Chromium Framework for Upper and Lower Removable Partial Dentures
A Removable Partial Denture with a framework of cobalt chromium is definitive denture treatment. Definitive in a sense that it has excellent mechanical qualities and offers denture design possibilities that consider periodontal health of the abutment teeth, esthetics and patient comfort. The design of the framework should be simple as possible, with bases and major and minor connectors avoiding contact with free gingiva and contacting alveolar ridge or the palate approximately 3 mm from the teeth.
Provisional Dental Crown
Temporary / Provisional Dental Crown is usually made of acrylic resin. It is cemented on tooth 11 (upper right central incisor), after tooth preparation to protect the tooth while the final / permanent dental crown is being fabricated. The final restoration for this case is all-ceramic dental crown.
