Bridge failures result in clinical complications and patients can present with: Management of bridge failures depends upon the extent and type of failure and these can be prevented through forming a thorough treatment plan with the patient as well regularly emphasising the importance of maintaining a very good level of oral hygiene after the bridge has been placed. These forces are transmitted to the abutment(s) via the prosthesis. Once stable periodontally compromised teeth may be used as abutments, depending on the crown to root ratio described below. Roots that curve apically provide increased support compared to those which have a fixed taper. The bridge is made and fitted shortly after the teeth are filed down. To remove dental bridges, your dentist will need to ‘break’ the bridge sectioning it into multiple pieces, this results in the bridge being permanently damaged and a new bridge will need to be made. Dome Pontic (also known as bullet or torpedo shaped), Ridge Lap Pontic (also known as Full Saddle Pontic). [3], Ante's law, states that the roots of abutment teeth must have a combined periodontal surface area in three dimensions that is more than that of the missing root structures of the teeth replaced with a bridge, is used in bridgework design. The total number of units in a bridge is equal to the number of pontics plus the number of abutment teeth. This may be due to inadequate bone levels, expense or patient not wanting to receive implants. This machine uses CAD/CAM technology (computer-aided design/manufacturing technology). First off, the temporary bridge is removed and the underlying teeth cleaned up. For the modified ridge lap design the pontic only contacts the buccal aspect of the alveolar ridge.

When the area is numb, the teeth in question are filed down. [17] Provisional bridges can either be made of acrylic resins or metal. A few final adjustments may be needed, for example to the bite. [3], Vital teeth are preferred to endodontically treated ones for bridge abutments. [3], The pontic and retainer are remote from each other and connected by a metal bar. The longer the span, the more deflection occurs. Salvin Dental Item #SECTION-BUR-703FG. GYPSUM PRODUCTS It is a mineral mined in various parts of the world chemically the gypsum produced for dental applications is pure calcium sulfate dihydrate [CaSO4.2H2O]. #SECTION-BUR-703FG.

Design of choice for replacing single anteriors, Straightforward to construct in the laboratory, Patients are able to maintain good oral hygiene as it is easy to clean, Limited retention due to small surface area, Appropriate positioning on cementation may be complex. [4][10], Torquing forces can occur when the pontic lies outside the interabutment axis line as the pontic acts as a lever arm. Part 1- Assessment and Design", "Incorporating modified ovate pontic design for anterior tooth replacement: A report of two cases", "Division of pontics according to shape and relation to the mucosa. Dental bridge procedure complete and bridgework in place.. Hard to spot? The mold is taken using a rubber putty material. As a way of fixed retention after orthodontic treatment or extraction.

Aesthetic failures: These can occur at the time of cementation and include; colour mismatch, roughness of margins or improper tooth contour.
