Partial or total edentulousness has a significant impact on quality of life both functionally and aesthetically.

TBR® Tissue Level Z1 Implants allow the patient to prevent bone resorption and maintain facial tissue and musculature support. At the functional level, the patient who benefits from implant treatment regains normal masticatory function with all the benefits on the quality of life that this can bring him.

Due to the osseointegration of the implant and the biocompatibility of the materials used, the implant treatment remains effective in the long term and makes it possible to maintain the aesthetics of the smile.

Many adults have one or more missing teeth. The negative consequences of partial or total edentulousness are numerous in the orofacial sphere:

• Edentulousness causes a strong aesthetic deficit due to the lack of support of facial tissues and musculature;
• Edentulousness generates a functional deficit that can have significant repercussions on the nutritional status of the affected subject;
• Edentulousness is accompanied by bone resorption of the jawbones which is inevitable in the absence of implant treatment;
• In addition, the resulting feelings of discomfort and fragility are experienced as a real psychological handicap by the patient, partially or totally edentulous, which can then have significant repercussions on his social life.

TBR® Tissue Level Z1 implants are intended for placement in the maxillary or mandibular arch in partially or completely edentulous patients for prosthetic restoration in the following cases:

• Single edentulousness,
• Intercalary edentulousness,
• Terminal edentulousness,
• Total edentulousness.

The following clinical conditions must be observed before placing a dental implant:

• Sufficient quality and volume of bone support;
• Healthy oral condition;
• no contraindications for implant setting

The procedure used to accomplish its intended use is as follows:

• The receiving implant site is prepared using an established drilling sequence then the implant is placed in this site: the body of the implant (in titanium) has an endosseous position while the ring (in ceramic) remains transgingival;
• After an osseointegration time, the final prosthetic abutment will be loaded on the implant.

The expected benefits of this surgery are to improve the quality of life of patients, to recover the chewing function and the aesthetics of the smile.
