Plain English summary of protocol

Background and study aims
OSSIX Volumax is already approved for sale product that is used in various dental procedures together with bone fillers. The purpose of the study is to see OSSIX Volumax safety and performance also in a thickening of the jaw treatment without other bone fillers.
The study aims to compare a treatment of jaw thickness improvement with OSSIX® Volumax compared to FibroGide®

Who can participate?
Adults over the age of 18 years that need to have a dental implant and have a narrow jaw

What does the study involve?
The study involves a standard dental implantation operation. The study starts with a dental operation and a patient will be followed up with standard tests and scans for 1 year.

What are the possible benefits and risks of participating?
A benefit for a patient is to have a thicker jaw which will assist better esthetic and functional results of dental treatment.
A risk in this case is similar to every standard dental procedure which includes pain, minor swelling.

Where is the study run from?
Bologna University (Italy)

When is the study starting and how long is it expected to run for?
September 2021 to March 2025

Who is funding the study?
Datum Dental Ltd (Israel)

Scientific titleA prospective, randomized controlled trial to evaluate correction of ridge contour deficiency using OSSIX® Volumax vs Fibro-Gide.
Study acronymvolumax SA
Study objectivesThe treatment of tissue augmentation with OSSIX® Volumax is non-inferior to the treatment with FibroGide as will be evaluated after 12 months from the treatment day.
Ethics approval(s)Approved 16/02/2022, Bologna Ethics Committee (Comitato Etico di Area Vasta Emilia Centro della Regione Emilia-Romagna, presso IRCCS Azienda Ospedaliero – Universitaria di Bologna, Policlinico S.Orsola-Malpighi, Via Albertoni, 15 – 40138 BOLOGNA, Italy; no telephone number provided; comet.speri@ausl.bologna.it), ref: 32-2022-DISP-AUSLBO
Health condition(s) or problem(s) studiedDental ridge contour deficiency
InterventionOSSIX® Volumax is a biodegradable and biocompatible collagen scaffold designed to support the formation of new alveolar bone and new attachment apparatus in teeth when the technique of Guided bone/tissue regeneration is utilized.

Fibro-Gide® is one of the available collagen scaffolds/matrices specifically designed for soft-tissue regeneration.

Subjects will be randomized into one of the treatment arms:
Study arm 1: OSSIX Volumax
Study arm 2: Fibro-Gide

Treatment indication: patients who need 1-3 dental implant with soft tissue deficiency.
The study device (or the control device) will be placed together with implant placements and healing abutments placement

Total duration of the study is 13 months. This including the screening period, the surgery of implantation, and the follow up visits.

The randomization will be done through the EDC system.
Intervention typeDevice
Pharmaceutical study type(s)
PhasePhase III
Drug / device / biological / vaccine name(s)OSSIX® Volumax
Primary outcome measureMeasuring the width of the ridge by intra oral scanner at 6 and 12 months
Secondary outcome measures1. Volumetric changes of the augmented site calculated by intraoral scan impression (mm³) at 6 and 12 months
2. Soft tissue healing measured by clinical evaluation at the surgery site at 6 and 12 months:
2.1. Keratinized tissue width on the buccal side of the two neighboring teeth; measured from a fixed referenced point to the mucogingival line (mm)
2.2. Wound closure (according to the wound healing index) at all time points.
2.3. Membrane/scaffold exposure, color, redness, and swelling, inflammation
2.4. Bleeding on probing (BOP)
2.5. Periodontal probing depth (PPD)
2.6. Clinical attachment level (CAL)
2.7. Recession depth (RD)

Exploratory:
1. Evaluation of OSSIX® Volumax clinical bone formation parameters from CBCT superposition:
1.1. Radiographic bone changes (horizontal and vertical) change in mm at 12 months
1.2. Implant stability (ISQ) and survival at 12 months
2. Esthetic outcome determined by a masked and calibrated examiner evaluated the results with predefined questionnaire at 12 months
3. Patient subjective oral health impact profile will be assessed with the OHIP-14 questionnaire at 2 weeks
4. Documentation of the related adverse events at all visits

Safety:
1. The safety will be assessed by evaluation of the number and severity of documented adverse events such as wound closure complications) and concomitant medications that will be recorded at all visits during the entire study period.
