Clinical Trial Summary

This study follows subjects who have agreed with their dentist that their failing teeth or missing teeth all need replacing. This study follows their standard routine care with some additional assessments. The dental treatment option that replaces a whole arch or both arches (upper and lower jaws) of the mouth is call "Teeth in a Day" and information on the use of the JUVORA™ Dental Disc during this treatment is what is being collected as part of this study along with subjects follow-up care.

Description:

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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Technical Satisfaction not related to the patient	Data collected during the Laboratory processing of the JUVORA™ Dental Disc into the prosthesis.; Infrastructure manufacturing issues? Framework integrity issues? Veneer adhesion issues?	between 4 - 6 months prior to fixture in the patients mouth.
Primary	Survival of the Prosthetic	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")	12 months
Secondary	Patient quality of life assessment using a patient questionnaire.	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.	6 weeks 6 & 12 months
Secondary	Oral and dental:Patients will be assessed for a history of Bruxism (grinding of the teeth).	If patients have suffered with Bruxism they will be asked if they have been wearing their night guard during their dental treatment.	6 weeks 6 &12 months
Secondary	Oral and dental: Patients will be checked for occlusion.	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)	6 weeks &12 months
Secondary	Survival of the implant in the patients mouth.	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).	12 months
Secondary	Success of the implant in the patients mouth.	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.	12 months
Secondary	Success of the implant in the patients mouth according to marginal bone resorption.	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.	12 months
Secondary	Success of the implant in the patients mouth according to the presence of Peri-implantitis.	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)	12 months
Secondary	Success of the implant in the patients mouth according to modified plaque index (mPI).	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	12 months
Secondary	Success of the implant in the patients mouth according to Modified Bleeding Index (mBI).	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	12 months
Secondary	Success of the implant in the patients mouth according to the probing depth.	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).	12 months
Secondary	Success of the implant in the patients mouth according to Soft Tissue Reactions.	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.	12 months
Secondary	Success of the implant in the patients mouth according to Mechanical Complications.	Complications related to the implant include implant fracture, abutment/screw fracture and loosening will be reported.	12 months
Secondary	Success of the prosthesis assessed according to specific criteria and in accordance with the ITI Treatment Guide Volume 8.	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).	12 months
