Implant-based prostheses can be cement-retained, screw-retained or a combination of both (Fig 1). By definition, an abutment is a component that is intermediate between the implant and the restoration and it is usually screw...
Patients wearing complete dentures often suffer from esthetic and functional discomfort and compromised denture retention and chewing function. Denture adhesives are often applied. Many patients perceive this...
The surgeon should be standing or be seated behind the supine patient. Bilateral truncular anesthesia is needed. The incision can be crestal or at a distance in the labial fold. Presence of keratinized tissue both labially and palatally should...
Incision can be made either on top of the crest or at some distance in the labial fold. The outcome for both approaches seems comparable. A sagittal release incision at the midline eases the reflection of the labial mucoperiosteum. It is logical to try to achieve...
Advantages of abutment-supported prostheses are 1) When implants are not parallel to each other, the use of angulated abutments can "correct" for the non-parallelism 2) Angulated abutments are available for a screw-retained prosthesis and 3) Custom abutments can be...
Any intra-oral surgical intervention begins with the incision and finishes with a suture or gluing. Indications for a crestal incision include one-stage surgeries where the implant or abutment is non-submerged and is piercing into the oral...
Traditional endosseous oral implant treatment protocols ad modum Brånemark required a variable healing period (usually 3-6 months) before prosthesis placement. The healing period was considered necessary to achieve osseointegration and establish a load-bearing interface...
The aims of peri-implant soft tissue management in the edentulous mandible are the eventual reconstruction of attached gingiva or immobilizing the soft tissue at the implant-soft tissue interface. Vestibuloplasty means deepening of the...
This is the reversible inflammatory process in the soft tissues around functioning implants. Peri-implant mucositis occurs in almost 60% of subjects (± 30% of sites), restored with implants. Diagnosis is stated by clinical examination: redness, ...
Inflammation can be limited to the soft tissue around the implant (mucositis) or involve the underlying bone tissue as well (peri-implantitis). Infection can be caused by various risk factors, such as inadequate hygiene and patient compliance...
Presence/number of implants influences aerobe and anaerobe species in saliva and on tongue in edentulism. Subgingival microbiota in periimplantitis vary according to studies. Less periodontal pathogens than in partial edentulism. Prevotella nigrescens,...
Whenever possible, provisional restorations should be fabricated to simulate the desired definitive prosthesis in form, albeit with different and less durable materials. The lessened durability and functional capacity of a provisional restoration...
The patient with a terminal dentition and who faces total teeth extractions can choose from a number of treatment options from immediate complete denture to one of the implant supported protocols.
Immediate dentures are chosen by patients who are unwilling...
Wound closure ensures and accelerates wound healing by protecting the site and influencing migration of keratinocytes over the granulation tissue. Some wound eversion maximizes epidermal approximation. Square knots, with two ties in one direction and a reverse...
