This prospective, single-center, interventional post-market clinical follow-up (PMCF) study aims to evaluate the early-term (24 months post-implantation) safety and efficacy of CE-marked BIODENTOSS® and DWC ® Dental Implants and Superstructures in patients requiring dental restoration for tooth loss.
18 years of age or older,
Male or female,
Subjects with missing tooth who require dental implant treatment,
At least 2 months elapsed since tooth extraction,
Suspected or confirmed pregnancy or breastfeeding,
Disorders preventing adequate daily oral hygiene,
Hypersensitivity/allergy to titanium or implant components,
Inappropriate interarch relationship or parafunction (e.g., bruxism),
Parallel
BIODENTOSS Bone-Level Dental Implant and Superstructures
DeviceSurgical placement of CE-marked BIODENTOSS bone-level dental implants, available in conical or cylindrical models, with diameters ranging from 3.4 mm to 6.0 mm and lengths from 7.5 mm to 13 mm. Implants feature an SLA (Sandblasted, Large-grit, Acid-etched) surface texture and a 22-degree conical internal hex connection. Following an osseointegration period, prosthetic restoration will be completed using compatible superstructures, including cover screws, healing abutments, and various types of prosthetic abutments based on clinical indications.
DWC Bone-Level Dental Implant and Superstructures
DeviceSurgical placement of CE-marked DWC bone-level dental implants, available in cylindrical or active threaded models, with diameters ranging from 3.3 mm to 4.8 mm and lengths from 8 mm to 15 mm. Implants feature an SLA (Sandblasted, Large-grit, Acid-etched) surface texture and a 22-degree conical internal hex connection. Following an osseointegration period, prosthetic restoration will be completed using compatible superstructures, including cover screws, healing abutments, and various types of prosthetic abutments based on clinical indications.
Implant Success and Satisfactory Survival Rate
The percentage of functional implants in each cohort meeting the 2007 International Congress of Oral Implantologists (ICOI) Pisa Consensus Conference Health Scale criteria. Multiple clinical/radiographic parameters (pain, mobility, bone loss, exudate) are aggregated to classify each implant into a single category: Group I (Success: no pain/mobility, \<2mm bone loss, no exudate); Group II (Satisfactory Survival: no pain/mobility, 2-4mm bone loss, no exudate); Group III (Compromised Survival: potential sensitivity, no mobility, \>4mm bone loss \[\<50% of implant body\], pocket depth \>7mm, potential exudate); or Group IV (Failure: pain, mobility, bone loss \>1/2 implant length, or uncontrolled exudate). To arrive at the single reported value, data are aggregated by calculating the combined percentage of implants classified into Group I and Group II out of the total implants evaluated in each cohort.
Implant Stability Measured by Resonance Frequency Analysis
Quantitative assessment of implant stability within each independent cohort using non-invasive Resonance Frequency Analysis (RFA). Individual implant stability will be reported based on the Implant Stability Quotient (ISQ) scale, ranging from 1 to 100. Higher values indicate greater stability, with an ISQ score ≥ 70 reflecting high stability.
Percentage of Implants With Zero Clinical Mobility
Assessment of post-loading implant stability evaluated via manual clinical examination. Clinical stability is measured by vertical and horizontal forces and graded using Mühlemann's Mobility Index, which ranges from 0 to 4 (where 0 indicates normal/physiological movement and 4 indicates vertical mobility). The single reported value will be the percentage of implants within each independent cohort achieving a mobility index score of "0" (lack of clinical mobility), indicating successful osseointegration.
Incidence of Complications and Adverse Events
Safety data will be collected by recording all adverse events (AEs) and complications encountered during the 24-month follow-up period. This includes intraoperative complications (e.g., bone fenestration/dehiscence, nerve injury), device-related failures (e.g., implant fracture, loss of stability), and any postoperative adverse events (e.g., infection, peri-implant mucositis, or prosthetic component loosening).
Marginal Bone Loss (MBL)
Radiographic assessment of bone level changes (mesial/distal) using digital panoramic/periapical radiographs.
Chewing Function and Chewing Satisfaction
Assessed independently within each cohort. Chewing function will be verified via clinical occlusion control using articulation paper. Patient chewing satisfaction will be scored directly by the participant using a 5-point Likert scale (ranging from 1: not satisfied at all, to 5: very satisfied).
Oral Health-Related Quality of Life (OHRQoL)
Assessed independently within each cohort using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. The scale consists of 14 items scored on a Likert scale, with total scores ranging from 0 to 56. Lower overall scores indicate superior OHRQoL and better clinical outcomes.
