Types Of Dental Implants Crowns PreciousPalladium-Silver ISO13485
SPACE REQUIREMENTS FOR DENTAL IMPLNATS
• There should be adequate interdental and inter-occlusal space for an implant restoration.
• There should be sufficient space for the implant to be placed in the bone without compromising adjacent structures.
• Where implants are placed between teeth or adjacent to each other there should be sufficient space to allow normal soft tissue contours around them. Implants should be fully covered by the bone. Where there is insufficient bone augmentation procedures should be considered.
• Anatomical structures may prevent the simple placement of dental implants in the posterior maxilla and posterior mandible.
• Bone concavities or thin ridges may compromise implant placement.
• The effects of gross resorption following tooth extraction and the presence of flabby ridges make implant placement more difficult.
• Care must also be taken with implant placement if there is a large incisive canal or submandibular fossa.

INDICATION
The decision to provide a crown or fixed bridge whether tooth or implant - supported depends on many factors, including:
• The motivation and aspirations of the patient.
• The oral and general health of the patient.
• The condition of the remaining teeth and tooth tissues, the periodontal condition and oral hygiene maintenance.
• Analysis of the benefits, disadvantages and long-term consequences of providing a crown or fixed prosthesis.
• Complications which limit the likelihood of clinical success.
• The skill and experience of the clinician. In all situations, the clinical advantages and long-term benefits of crowns and fixed bridges should justify such treatment and outweigh their disadvantages. They should only be undertaken in those situations in which such advanced restorative care will clearly contribute to the oral health and welfare of the patient. The replacement of failed crowns and bridges and the teeth or implants which support them should be conditional on an understanding of the aetiology and successful preventive management of the cause(s) of failure.
