Causes of Injury in Tooth Prep
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.

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.

Removable Partial Denture with Cobalt Chromium Framework with premature contact on the occlusal and cingulum rests.
In
Removable Partial Denture one piece casting, it is necessary to check and adjust everything in wax pattern stage before the metal framework is casted. It is difficult to adjust the metal framework without disrupting its fit.

Tooth preparation for endodontically treated teeth for Fixed Partial Denture
Preop Periapical X Ray Showing Endo Treated Central and Lateral Incisor
Root canal
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.
Provisional Dental Crowns
Procedure
Tooth preparation for endodontically treated teeth is a 3 stage operation
1. Removal of the root canal filling material to the appropriate depth.
2. Enlargement of the canal.
3. Preparation of the coronal tooth structure.

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.

A low cost technique for overdenture treatment is the transformation of Patient’s existing removable partial denture into a complete denture. It has an advantage that the patient is familiar with the denture, thus adaptation is likely to be uncomplicated. The first step in this procedure is to take an impression for relining the denture. Second is an alginate impression comprising the denture and the remaining natural teeth. The impression is filled with plaster, and the plaster teeth are removed from ensuing model.
