What are contraindications for fixed prosthodontics?
Contraindications for Fixed Prosthodontics Necessary supportive tissues are diseased or missing. Suitable abutment teeth are not present. The patient is in poor health. The patient is not motivated to have the prosthesis placed.
What is the difference between fixed and removable prostheses?
The difference between the two options is that removable implant-supported dentures can be snapped on and off of the abutments whenever you need to remove them, while fixed dentures are permanent and can only be removed by a dentist.
What are fixed dentures?
Permanent or “fixed” dentures refer to a prosthetic tooth replacement that is permanently held in place by denture implants. During dental implant surgery, your dentist will secure your fake tooth replacement by screwing one or more dental implants into the jawbone.
What is a fixed crown?
Fixed Dental Bridge Replacing Single Tooth. Implant-supported Dental Crown. This treatment option involves placement of a titanium dental implant into the original bone pocket or alveolus where the missing tooth used to be.

What are the indications for provisional coverage?
To reduce sensitivity and discomfort of a prepped tooth, to protect the margins of the prep, maintain function and esthetics, and to prevent shifting of adjacent and opposing teeth. What are the indications for placing provisional coverage? They must be adequate to touch the adjacent teeth.
Why are fixed and removable prostheses used in dentistry?

What should be considered before starting prosthetic treatment for gum disease?
Before starting prosthetic treatment, the condition of the periodontal tissues should be assessed for their oral hygiene status, and gingival and periodontal conditions.
What causes alterations in periodontal tissues during prosthetics?
Alterations in periodontal tissues occur during prosthetic treatment with fixed prosthetic constructions, which take place during the initiation of the adaptive and regenerative processes [ 86 ].
Does periodontal health affect the longevity of prosthodontic restorations?
Periodontal health plays an important role in the longevity of prosthodontic restorations. The issues of comparative assessment of prosthetic constructions are complicated and not fully understood.
