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
• 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
• Care must also be taken with implant placement if there is a
large incisive canal or submandibular fossa.
• To determine the patient’s requirements and expectations and to
gain an informed opinion of the patient’s suitability for treatment involving the use of crowns or
• To obtain a history, which includes details of all previous
conditions and experiences of relevance including information
pertaining to any adverse reactions to treatment, the
administration of drugs and the use of materials.
• A medical history is mandatory for all patients. Treatment
involving the provision of dental implants should additionally
include questioning regarding the following recognised risk
• Bisphosphonate therapy.
• Uncontrolled diabetes.
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.
