Extraction of teeth with persistent periapical lesions requires a specific drilling protocol to remove infected bone, to reach healthy trabecular bone and start up a bleeding. Residual dens sclerotic bone may harbor latent pathogenic microorganisms for a...
The peri-implant mucosa consists of an externally located keratinized oral epithelium, which is connected to the peri-implant junctional epithelium facing the abutment. The latter extends approximately 2 mm apical to the...
Cement-retained restorations are a traditional design to attach a restoration (crown, bridge) to an implant-retained abutment, similar to cementing a crown or bridge restoration on a natural tooth. With the traditional, relatively...
Frameworks are veneered with veneering materials, to design the esthetics and shape of the definitive restoration. Framework material options for acrylic veneering include titanium, (CrCo) Cobalt - Chrome and precious alloys...
Frameworks can be made from titanium, zirconia, precious alloys and Co-Cr base alloys and can be cement-retained or screw-retained. With minimal bone resorption, a ceramo-metal restoration is preferable to accommodate interarch...
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...
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,...
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...
The gingiva is tightly connected to the underlying periosteum. It is globally keratinized and has a stippled surface. Its color varies from pink to brown or even black, depending on race and/or melanin deposits. It can be distinguished from alveolar mucosa, which...
