The main question it aims to answer is:\n\n\\- What is the survival outcome of single teeth implant-supported prosthesis using Poly-ether-ether-ketone?

To test this, the study design to be used will be a single centre, prospective, observational cohort study to evaluate the short term outcome of fixed prosthetic implant-supported rehabilitations. The sample of this study consists in 10 patients consecutively treated. The cohort will be evaluated after 6 months and 12 months after dental loading and annually thereafter as long as the patient is willing regarding: prosthetic survival including repair and relining, implant survival, marginal bone resorption, incidence of mechanical complications (loosening or fracture of prosthetic components), biological complications (peri-implant infection, suppuration, abscess, fistulae), patient tissue reaction, aesthetic examination including staining, colour stability and anatomical form; patient in mouth comfort and quality of life using the Oral Health Impact Profile OHIP-14 questionnaire; and assessment of prosthetic preparation (technician satisfaction), laboratory preparation time, clinical operative time and costs for economical purposes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients rehabilitated with a single crown supported by and implant in immediate function;\n* Subjects who, in the opinion of the Investigator, are able to understand this clinical study, co-operate with the procedures and are willing to return to the clinic for all the required post-operative follow-ups;\n* Subjects who are able to give voluntary, written informed consent to participate in this clinical study and from whom consent has been obtained.\n\nExclusion Criteria:\n\n* Female Subjects who are pregnant;\n* Subjects who are known drug or alcohol abusers or with psychological disorders that could affect follow-ups or treatment outcomes;\n* Subjects who are currently enrolled in a clinical study;\n* Subjects requiring or currently having ongoing orthodontic treatment;'}, 'identificationModule': {'nctId': 'NCT05589532', 'acronym': 'PEEKPilotST', 'briefTitle': 'Single Tooth Implant-supported Fixed Prosthetic Rehabilitation Using PEEK.', 'organization': {'class': 'OTHER', 'fullName': 'Malo Clinic'}, 'officialTitle': 'Rehabilitation of Single Teeth Edentulism Through the Use of Polyetheretherketone (PEEK) Prosthetic Single Crowns Supported by Dental Implants', 'orgStudyIdInfo': {'id': 'PEEKPilotST'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Prosthetic single-tooth prosthesis using PEEK', 'description': 'An implant-supported single tooth prosthesis using a PEEK polymer in its composition', 'interventionNames': ['Device: Prosthetic single-tooth prosthesis using PEEK']}], 'interventions': [{'name': 'Prosthetic single-tooth prosthesis using PEEK', 'type': 'DEVICE', 'otherNames': ['PEEK prosthesis'], 'description': 'A single tooth implant-supported fixed prosthesis using PEEK polymer in its composition delivered as definitive prosthesis.', 'armGroupLabels': ['Prosthetic single-tooth prosthesis using PEEK']}]}, 'contactsLocationsModule': {'locations': [{'zip': '1600-042', 'city': 'Lisbon', 'state': 'Lisbon District', 'country': 'Portugal', 'facility': 'Malo Clinic', 'geoPoint': {'lat': 38.72509, 'lon': -9.1498}}], 'overallOfficials': [{'name': 'Miguel A de Araújo Nobre, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Director of Research, Development and Education'}]}, 'ipdSharingStatementModule': {'infoTypes': ['SAP'], 'timeFrame': 'Upon study completion and for 8 years.', 'ipdSharing': 'YES', 'description': 'Anonymized database containing the study variables', 'accessCriteria': 'Upon solicitation to the Investigators'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Malo Clinic', 'class': 'OTHER'}, 'collaborators': [{'name': 'Invibio Ltd', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
