About this study

Official title: Prospective, Multi-center, Randomized, Single Blinded and Parallel Controlled Clinical Investigation to Assess the Performance, Safety and Benefit of the Wishbone HA Medical Device, a Deproteinized Bovine Bone Material, as a Bone Graft Substitute in the Socket Management Indication Requiring Bone Grafting Procedure Before Implant Placement.

This investigation is a pre-market, prospective, multi-center, randomized, single blinded, parallel controlled clinical investigation performed in at least 5 clinical centers for confirmatory purposes of the use of WHA as intended in the filling of extraction sockets to enhance preservation of the alveolar socket.

Read the detailed description

In this study, the subjects will be pseudonymized and randomized in a 1:1 ratio between WHA and the selected comparator device Bio-Oss®. The sample size of the study has been computed based on a non-inferiority test between Bio- Oss® and WHA for device performance for the filling of extraction sockets. A total of 96 subjects will be enrolled.

The results will be used to demonstrate the safety, performance and benefit of the product WHA in the socket indication in compliance with the MDR 2017/745.

The endpoints are all accurately based on objective measurements:

  • Primary Endpoint: Bone reconstruction as measured by CBCT (in mm) after bone grafting procedure.
  • Secondary Endpoints:
  • Evaluation of implant stability at placement.
  • Assessment of bone density at the time of implant insertion.
  • Implant osteointegration at 3months after implant placement.
  • Evaluation of implant survival and success at 3-, 6-and12-months, 3-and 5- years after implant placement.
  • Rate of all Adverse Device Events (incidence, type, relatedness, severity, seriousness) from the time of grafting procedure up to 5 years after implant placement.
  • Patient satisfaction 6- and 12-months after implant placement.
  • Evaluation of the Sulcus index (peri-implant marginal tissue health status) at 6- and 12-months after implant placement.

Tooth extraction and bone graft procedure

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tooth extraction and bone graft procedureDevice

    The subject will receive a flash dose of 2 gr of amoxicillin or 600 mg of Clindamycin 1 hour before the surgery.

    Tooth will be extracted using gentle techniques to guarantee an atraumatic extraction. If the socket presents insufficient bleeding, the clinician must use an appropriate procedure to induce bleeding. The extraction site must be carefully cleaned. Extraction socket will then be filled with WHA or Bio-Oss previously hydrated with saline solution (0.9%). Extraction socket packed with the graft will be covered with a collagen sponge (Geistlich Mucograft® Seal) and sutured (cross suture, Vicryl rapide 4.0).

    If required, a limited connective tissue graft can be placed in the vestibular region.

    A CBCT scan will be performed after the bone graft procedure, i.e., after the extraction socket and the biomaterial placement, to measure the initial bone width.

    The safety of the investigational device will be evaluated.

Study groups in NCT06383377
Study groupRoleWhat they receive
Bio-Oss®Active comparatorTooth scheduled for extraction will be removed in the least traumatic way. The socket will be filled with the comparator (Bio-Oss® Geistlich, granules 0.25 - 1mm). Two follow up visits to monitor the healing process will take place at 2 and 6 weeks after surgery. Implant placement will be performed 4 months after the regenerative procedure. Implant loading will be allowed after having waited a minimum of 3 months after the implant placement and after a control visit. The implant survival and success will be assessed at 3, 6 and 12 months after implant placement. A long-term follow-up will evaluate the implant survival and success at 3 and 5 years post implant placement.

Receives: Device: Tooth extraction and bone graft procedure

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bone reconstruction as measured by CBCT (in mm) after bone grafting procedure.

    Bone thickness will be measured using CBCT scan 4 months after the bone augmentation procedure and just before implant insertion. The most apical point from the extraction socket defined at baseline will be set as a reference. The vertical reference line will be drawn in the center of the extraction socket crossing the apical reference point. The horizontal reference line is drawn perpendicular to the vertical line crossing the apical reference point. Based on these marks, 3 measurements will be done at 1, 3 and 5 mm from the top of the crest.

    Measured: one year

Secondary outcomes (8)
  1. Assessment of the bone density at implant placement.

    Assessment of the bone density on the first and second half of the defect at implant placement using a Likert scale at implant placement.

    Likert scale:

    1. = soft bone
    2. = medium bone
    3. = hard bone

    Measured: one year

  2. Evaluation of the implant primary stability.

    Implants primary stability determined by using the torque wrench at implant placement.

    Measured: one year

  3. Assessment of the implant osteointegration after implant placement

    Taping of the implant and a rotation test will be performed. A torque wrench will be used at 10Ncm for the rotation test.

    Measured: 15 months

  4. Implant survival rate and success evaluated at 3-, 6- and 12-months and 3- and 5- To evaluate implant survival and success 3-, 6- and 12- months and 3- and 5-years after implant placement

    At 3-, 6- and 12-months and 3- and 5-years after implant placement, implant survival will be assessed by answering if:

    1. The implant remains in the jaw.
    2. The implant is damaged to the extent that it cannot be restored.

    The success of the implant will be assessed with the criteria from Buser et al.:

    • Absence of persistent subjective complaints such as pain, foreign body sensation and/or dysesthesia
    • Absence of a peri-implant infection with suppuration
    • Absence of mobility
    • Absence of a continuous radiolucency around the implant

    Measured: 5 years

  5. Collection of all adverse events (AEs) related to the device and/or procedure, and assessment of incidence, type, severity, seriousness

    At a minimum prior and after implantation, and at each follow-up thereafter, the following treatment-emergent local AEs, namely any local AE for which the start date is on or after the date that the intervention began, will be assessed for severity, seriousness, and relatedness to the device and/or procedure and recorded in the eCRF using standard medical terminology:

    • Pain
    • Flap sloughing
    • Infection
    • Inflammation at the surgical site
    • Swelling at the surgical site
    • Bleeding
    • Bone loss
    • Loss of graft material

    Measured: 5 years

  6. Evaluation of patient satisfaction at 6- and 12-months after implant placement using questionnaire.

    The questionnaire will focus on the following questions:

    • How satisfied are you with the length of procedures and how they affected your daily functioning?
    • How satisfied are you with the function and aesthetics of the final restoration?
    • How satisfied are you with the pain associated with the treatment?

    The scale for each of these questions will be as follows:

    0= Not satisfied

    1. Fairly satisfied
    2. Satisfied
    3. Extremely satisfied

    Measured: 2 years

  7. Evaluation of the peri-implant marginal tissue health status at 6 and 12 months after implant placement.

    Assessment of the peri-implant marginal tissue health status using Sulcus Bleeding Index (mBI)

    0= No bleeding when a periodontal probe is passed along the gingival margin adjacent to the implant;

    1. Isolated bleeding spots visible;
    2. Blood forms on a confluent red line on the margin;
    3. Heavy or profuse bleeding.

    Measured: 2 years

  8. Evaluation of the evolution of the interproximal bone level 3- and 12-months after implant placement.

    The bone to implant neck distance will be evaluated at the mesial and distal aspect from the implant at 3- and 12-months post implant placement.

    Measured: 2 years

Model description
The parallel group will be treated with the product Bio-Oss® in a 1:1 randomization. Bio- Oss® is a natural bone mineral of bovine origin. Bio-Oss® is available as granules of spongious bone. Sterilization of Bio-Oss® is carried out by irradiation. Bio-Oss® has a macro- and microporous structure similar to human spongious bone. Bio-Oss® supports the in-growth of new bone at the implantation site by serving as a stable scaffold for osteoblasts; over time it is subject to the physiological remodeling process. Bio-Oss® is slowly resorbable, depending on the physiological environment of the individual patient, or integrated into the host bone. The highly purified osteoconductive mineral structure is produced from natural bone in a multistage purification process, adhering to the strictest safety regulations.
