|Missing Teeth||Device: Treatment with the JUVORA™ Dental Disc|
Over the last decade full-arch metal implant-supported prosthetics have been used as a replacement for missing teeth in edentulous (toothless) patients. The standard has been a titanium metal base. Due to its potential shock-absorbing properties and patients' demands for metal-free restorations, there is rising enthusiasm surrounding the use of High Performance Polymers (HPPs) such as the polyaryletherketone (PAEKs) as metal alternatives for such cases. The JUVORA™ Dental Disc is made from PEEK-OPTIMA™ polymer (Invibio Biomaterial Solutions) which allows efficient fabrication of reliable non-metal dentures by using CAD/CAM technology to manufacture precise, custom-fit prostheses. The JUVORA™ Dental Disc is indicated for the manufacture of: full-arch implant-supported dentures and implant bars; full and partial removable dentures and overdentures; crowns and 3-unit bridges.
This study aims to evaluate the short- and long-term clinical performance and patient satisfaction of the JUVORA™ full-arch implant-supported prostheses.
Two subjects will be included in a run-in phase and 10 subjects will be included in the main study.
The subjects will be followed-up at 6 weeks, 6 months, 12 months and for as long as willing yearly after the implant of the definitive prosthesis (artificial teeth).

Treatment with the JUVORA™ Dental Disc
Subjects receive the device as per normal standard practice, there are no other treatment arms for this prospective study.
Device: Treatment with the JUVORA™ Dental Disc
treatment with the JUVORA™ Dental Disc
- Survival of the Prosthetic [ Time Frame: 12 months ]Survival will be evaluated using the ITI Treatment Guide Volume 8 - Survival is defined as "is the prosthesis present in the mouth at the time of assessment ("presence or absence")
- Patient quality of life assessment using a patient questionnaire. [ Time Frame: 6 weeks 6 & 12 months ]Overall health-related QOL questionnaires - (Oral Health Impact Profile) OHIP - 14 measures peoples perceptions of the social impact of Oral Disorders on their well-being. Fourteen questions with 5 possible answers: Never, Hardly Ever,Occasionally, Fairly Often, Very Often. Questions are related to whether subjects have had problems with their teeth, mouth or dentures.
- Oral and dental:Patients will be assessed for a history of Bruxism (grinding of the teeth). [ Time Frame: 6 weeks 6 &12 months ]If patients have suffered with Bruxism they will be asked if they have been wearing their night guard during their dental treatment.
- Oral and dental: Patients will be checked for occlusion. [ Time Frame: 6 weeks &12 months ]
This is a way of checking when the teeth are clenched how many generalized number of contacts there are between the two arches (i.e., how many teeth are in contact between the upper and lower jaw arches)
- Amount of cantilever from the most distal implant for the left side will be recorded in (mm)
- Amount of cantilever from the most distal implant for the right side will be recorded in (mm)
- Survival of the implant in the patients mouth. [ Time Frame: 12 months ]Survival will be evaluated in accordance with the ITI Treatment Guide Volume 8. Survival is defined as 'is the implant present in the mouth at the time of the assessment' (presence or absence).
- Success of the implant in the patients mouth. [ Time Frame: 12 months ]Success will be evaluated in accordance with the ITI Treatment Guide Volume 8. Implants will be deemed to be successful if they are present:without implant fracture, without radiolucency changes from pre-treatment condition, without mobility, without pain, infection (suppuration, abscess and/or fistula), or paresthesia and without bone loss > 2mm.
- Success of the implant in the patients mouth according to marginal bone resorption. [ Time Frame: 12 months ]Success will be evaluated according to the marginal bone resorption (bone loss). Evaluated using a conventional digital panorex xray and measured. The measurements will be performed on the mesial and distal aspects of the implant platform and the lowest value will be recorded.
- Success of the implant in the patients mouth according to the presence of Peri-implantitis. [ Time Frame: 12 months ]Success will be evaluated according to the presence of Peri-implantitis (presence of inflamed mucosa with positive bleeding on probing and or suppuration ≥5mm and cumulative bone loss of ≥ 2mm and/or ≥3 threads of implant)
- Success of the implant in the patients mouth according to modified plaque index (mPI). [ Time Frame: 12 months ]
Success will be evaluated according to the Modified Plaque Index (mPI) will be evaluated by inserting a periodontal plastic probe 1 mm into the peri-implant sulcus running a circular movement all around the implant and measured in a scale between 0 to 3:
0 = no detection of plaque
- = plaque only recognized by running a probe across the smooth marginal surface of the implant
- = plaque can be seen by the naked eye
- = abundance of soft matter
- Success of the implant in the patients mouth according to Modified Bleeding Index (mBI). [ Time Frame: 12 months ]
Success will be evaluated according to the Modified Bleeding Index (mBI) evaluated by inserting a periodontal plastic probe 1 mm into the peri-implant sulcus running a circular movement all around the implant and measured in a scale between 0 to 3:
0 = no bleeding when a periodontal probe is passed along the mucosal margin adjacent to the implant
- = isolated bleeding spots visible
- = blood forms a confluent red line on mucosal margin
- = heavy or profuse bleeding
- Success of the implant in the patients mouth according to the probing depth. [ Time Frame: 12 months ]Success will be evaluated according to the Probing Depth. The depth of the peri-implant sulcus will be determined by measuring the distance from the mucosal margin to the base of the sulcus using a calibrated periodontal probe using minimal force (< 0.3M).
- Success of the implant in the patients mouth according to Soft Tissue Reactions. [ Time Frame: 12 months ]Success will be evaluated according to Soft Tissue Reactions. The presence or absence of oral mucosal disorders not related to peri-implant infection (e.g., reporting of allergic reactions, lichen planus) will be recorded.
- Success of the implant in the patients mouth according to Mechanical Complications. [ Time Frame: 12 months ]Complications related to the implant include implant fracture, abutment/screw fracture and loosening will be reported.
- Success of the prosthesis assessed according to specific criteria and in accordance with the ITI Treatment Guide Volume 8. [ Time Frame: 12 months ]
Success will be evaluated in accordance with the ITI Treatment Guide Volume 8. JUVORA™ prosthesis will be deemed to be successful if they are present:
- without complications (fracture of the veneering material, framework fracture and loss of retention of the prosthesis)
- with adequate 'in-mouth comfort': using a grading system between 0 (poor) and 10 (excellent).
- with adequate function (chewing): Function is defined as the chewing ability of the patient to chew different food types (meat, fruit, vegetables, salad) using a grading system between 0 (poor) and 10 (excellent).
- with adequate aesthetics: Aesthetic examination including surface luster and staining, colour stability, translucency, and anatomic form.
Also Attachment Performance:
Attachment performance will involve examination and recording of any issues related to attachment performance (presence or absence).
- Device Deficiencies reported for the JUVORA™ Dental Disc/prosthesis only: Inadequacy of medical device with respect to identity, quality, durability, reliability, safety and performance and includes malfunctions, user errors and inadequate labelling. [ Time Frame: 6 weeks 6 & 12 months ]
Device Deficiency data collected:
Date deficiency occurred, if it could have led to a medical occurrence:
if either a suitable action had not been taken or if intervention had not been made or if circumstances had been less fortunate
- If could have led to a Serious Adverse Device Effect (SADE)?
Which is a serious adverse event according to one of the criteria below and device related:
