Trusted Bone Regeneration
with Geistlich Biomaterials and Allodyn®
Allodyn®: Premium Allograft for Bone Regeneration
Why an Allograft Option Matters
Clinicians face a wide range of regenerative situations, and having different graft types available enables more personalised treatment planning. Human-derived allografts provide a natural tissue structure and a familiar biological environment, making them a valuable choice in selected regenerative procedures. Some clinicians appreciate their handling characteristics and remodeling profile, while certain patients prefer human-derived materials for personal or ethical reasons.
Offering an allograft alternative enhances the regenerative toolkit, supporting individualised planning with greater flexibility and choice.
Allodyn® (O.S.T. Laboratoires) is a high-quality bone allograft for dental surgery, ethically sourced from living donors during hip replacement procedures. Each donor undergoes rigorous screening, and full traceability is ensured. By preserving its natural collagen and mineral structure, Allodyn® provides a very good scaffold for bone regeneration. With over 25 years of clinical use, advanced sterilisation, and proven results, it offers reliable performance and biocompatibility for clinicians and patients alike. 1–4

Why Allodyn® Makes a Difference
Ridge Preservation in the Posterior Maxilla
Dr. Amit Patel Birmingham, UK
“If an immediate implant is not an option, I will preserve the ridge and I prefer to use an allograft to provide a faster turnover in this case to support the adjacent teeth.”
Initial Situation
Tooth 24 presented with severe buccal bone loss and a hopeless prognosis, requiring extraction. Oral health was good, with a minor gingival recession of 1–2 mm.
Therapeutic Approach
Following atraumatic extraction of tooth 24, the socket was thoroughly debrided with a curette. A Geistlich Bio-Gide® membrane was positioned buccally beneath the bone defect to protect the Allodyn® bone graft. The graft was placed into the socket, and the membrane was wrapped over it toward the palatal aspect. The site was closed with 5-0 Vicryl Rapide sutures.
Final Result
At 5 months, CBCT evaluation was performed to plan the next
My Advice
> Use Allodyn® for early placement if immediacy is not an option.
> In cases with adjacent teeth that have bone loss, I prefer to use an allograft for faster turnover.
> Consider open healing to preserve keratinised tissue.

Immediate Implant Placement in the Posterior Mandible
Dr. Alfonso Rao
Bristol, UK
“I always prefer to use a combination of allograft and Geistlich Bio-Oss® to optimize the regeneration and longterm outcome.”
Initial Situation
The patient presented with irreversible pulpitis on tooth 46. The endodontist deemed the tooth to have a poor prognosis due to the depth of the margins. The patient preferred to replace the tooth with an implant.
Therapeutic Approach
After atraumatic extraction, preserving the septum, the implant was placed carefully in the desired restorative position. The buccal wall was absent due to root morphology. Geistlich BioGide® membranes were positioned and secured with tacks before the socket was filled with Allodyn®. PTFE sutures were used in an open-healing approach to preserve keratinised mucosa.
Final Result
After healing, the implant demonstrated an ISQ of 77. A digital impression was taken, and a screw-retained crown was fabricated and fitted.
My Advice
> Use Geistlich Bio-Oss® for immediate implant placement in self-contained sockets.
> In one-wall defects, select Allodyn® alone or combine with Geistlich Bio-Oss® to enhance contour stability.
> Place the master pin before introducing the graft material to ensure optimal membrane fixation.
> Consider open healing to preserve keratinised tissue.

GBR Around Implants in the Anterior Maxilla
Dr. Amit Patel Birmingham,
UK
My Advice
> In minor defects such as buccal dehiscence, I use an allograft to gain new bone quicker.
> I always support my hard tissue grafts with a membrane to support the 360° vascularisation.
> I place a subperiosteal suture to provide stabilisation of the membrane.
“I always prefer to use a combination of Allodyn® and a Geistlich Bio-Gide® membrane to optimise the regeneration and long-term outcome.”
Initial Situation
The patient was referred by the general dental practitioner for consultation regarding implant treatment. Tooth 11 was missing, and the patient was dissatisfied with the partial denture, preferring a fi xed solution. Oral health was good, with an unremarkable medical history.
Therapeutic Approach
Following the slow-drilling protocol, the implant bed was prepared and the implant placed. A buccal dehiscence was noted. Autologous bone harvested during drilling was placed over the exposed threads, followed by Allodyn®. A Geistlich Bio-Gide® membrane was positioned over the graft and stabilized with a subperiosteal suture. The buccal flap was closed with 5-0 Vicryl Rapide sutures.
Final Result
A crown was fabricated and fitted. The patient was highly satisfied with both the aesthetic and functional outcome.

2-Stage GBR in the Anterior Mandible
Dr. Romain Ohanessian Toulon, France
“Allodyn® is a versatile and reliable grafting material, delivering predictable volume stability and natural integration for long-term aesthetic success.”
Initial Situation
The patient presented with terminal periodontal loss on tooth 31.
Therapeutic Approach
The treatment plan was to extract the tooth and perform simultaneous horizontal bone augmentation to reconstruct the buccal cortical plate and enable correct three-dimensional implant placement with navigated surgery.
Final Result
This case demonstrates the feasibility of bone regeneration in the anterior mandible, even in areas with limited bone thickness. The combination of Allodyn® and Geistlich Bio-Gide® enabled complete regeneration and a final prosthetic restoration that integrated harmoniously with the surrounding tissues after a guided provisional phase.
My Advice
> Use Allodyn® for GBR in the anterior region to optimise ridge contour and volume.
> Combine with a resorbable collagen membrane (Geistlich Bio-Gide®) to maintain space and stabilise the defect.
> Place implants in a prosthetically guided position to ensure predictable function and aesthetics.

2-Stage GBR in the Posterior Mandible
Dr. Romain Ohanessian Toulon, France
My Advice
> Use Allodyn® for GBR in the posterior region to optimise ridge volume and secure implant placement.
> Combine with a resorbable collagen membrane (Geistlich Bio-Gide®) to support the Sausage Technique™ by maintaining space and stabilising graft material.
> Guided surgery to ensure predictable function.
“The combination of Allodyn® and Geistlich Bio-Oss® provides sufficient graft volume for predictable dimensional stability and natural integration, supporting long-term implant success.”
Initial Situation
The patient presented with unilateral left posterior edentulism and vertical and horizontal bone loss.
Therapeutic Approach
The Sausage Technique™ was performed using the resorbable collagen membrane Geistlich Bio-Gide® combined with a graft mixture of Allodyn® and Geistlich Bio-Oss® to achieve sufficient volume for implant placement. After 4 months, a flap was raised and two implants were placed in the edentulous ridge.
Final Result
This case demonstrated bone regeneration in the posterior mandible using the Sausage Technique™, addressing both vertical and horizontal defects. Allodyn® and Geistlich Bio-Oss® together with Geistlich Bio-Gide® enabled complete regeneration and a prosthetic restoration that seamlessly integrates with surrounding tissues, ensuring long-term stability.

Sinus Floor Elevation
Dr. Amit Patel Birmingham, UK
“By using Allodyn® for lateral sinus floor elevation, I can place implants predictably at 5 months, reducing the timeline for my patients.”
My Advice
> For lateral window cases I always place a Geistlich Bio-Gide® membrane to protect the sinus floor prior to placing Allodyn®.
> I use Allodyn® to provide early turnover to reduce the time of healing allowing placement of implants after 5 months.
Initial Situation
The patient requested fi xed replacement of missing posterior teeth. Due to reduced vertical bone height, a sinus lift was required.
Therapeutic Approach
The sinus floor was elevated, and a Geistlich Bio-Gide® membrane was placed to protect the sinus membrane before filling the sinus cavity with Allodyn® bone graft. A Geistlich Bio-Gide® membrane was then placed over the lateral window to protect the graft. The buccal flap was closed using 5-0 Vicryl Rapide sutures.
Final Result
Five months postoperatively, the CBCT showed good consolidation of the Allodyn® bone graft, allowing placement of two implants in sites 25 and 26. The implants were left to integrate for three months before restoration.

Periodontal Surgery in the Anterior Maxilla
Dr. Azim Malik London, UK
“I use allografts in combination with enamel matrix derivatives to achieve enhanced outcomes in periodontal regeneration, ensuring long-term stability of the area and improved tissue integration.”
Initial Situation
The patient presented with a 12 mm periodontal pocket on the distal aspect of tooth 13, which was planned to serve as an abutment for a partial denture.
Therapeutic Approach
A mucoperiosteal flap was raised, and the defect was debrided. The root was conditioned with enamel matrix derivative. Cortico-cancellous Allodyn® particles were applied and covered with a Geistlich Bio-Gide® membrane, secured with periosteal sutures. After periosteal release, the flap was closed with mattress and interrupted sutures.
My Advice
> Allodyn® CS Fine can be reliably used for periodontal defect regeneration.
> The graft is easy to handle and adapt and may be combined with enamel matrix derivatives or REGENFAST® (Mastelli S.r.l.) to enhance outcomes.
> For wider or complex defects, use a collagen membrane such as Geistlich Bio-Gide®.
