BIOBRIEF
Mandibular Alveolar Ridge Split with Delayed Implant Placement
THE SITUATION
A healthy (ASA 1) non-smoker 63-year-old female presented to my office with Kennedy Class II partial edentulism in the mandibular right posterior quadrant for several years. She denied removable options and wanted dental implants to individually replace her missing teeth. The clinical and radiographic evaluation revealed atrophic mandibular bone height and width at site #’s 29, 30 & 31. The edentulous site required engineering prior to the placement of conventional dental implants and prosthetics.

download pdfTHE APPROACH
The goal is to provide adequate soft and hard tissue at edentulous site #’s 29, 30 & 31 in order to place dental implants and restore a stable balanced occlusion.
“The hard and soft tissue of the edentulous posterior mandible were inadequate to rehabilitate with dental implants.”
— Dr. Gregory Santarelli
THE OUTCOME
The patient summarized this challenging case very well – “I never imagined I would have fixed teeth again.” Geistlich Bio-Oss® and Geistlich Mucograft® allowed for retention of the hard and soft tissue volume to achieve our final result and for maintenance of the final prosthesis.

BIOBRIEF
Geistlich Mucograft® for the Treatment of Multiple Adjacent Recession Defects: A More “Palatable” Option
THE SITUATION
A 35-year-old male presented in my practice with a chief complaint of recession. Multiple buccal recession defects ranging 2-5 mm were noted by teeth #11-14 with a minimal amount of keratinized tissue on the buccal of #14. Bone levels were within normal limits with no loss of interproximal tissue observed. These recession defects are classified as Miller Class I recession defects. Typically, 100% root coverage is expected for recession defects of this type.
THE RISK PROFILE
| Low Risk | Medium Risk | High Risk | |
|---|---|---|---|
| Patient’s health | Intact immune system | Light smoker | Impaired immune system |
| Patient’s esthetic requirements | Low | Medium | High |
| Height of smile line | Low | Medium | High |
| Gingival biotype | Thick – “low scalloped” | Medium – “medium scalloped” | Thin – “high scalloped” |
| Bone defect(s) | Not present | Slight defect <2mm | Significant >3mm |
| Keratinized tissue | Adequate 5mm | Inadequate <5mm | Inadequate <3mm |
| Miller classification | Class I-II | Class III | Class IV |
watch videoTHE APPROACH
My treatment goals included completing root coverage of the recession defects and augmentation of the width of attached keratinized tissue by tooth #14. My patient had similar recession defects on teeth #3-6 which were previously treated with an autogenous sub-epithelial connective tissue graft. Instead of autogenous tissue grafting, Geistlich Mucograft®, a xenogenic collagen matrix, was used in conjunction with a coronally advanced flap.
“The patient was unhappy with the post-operative morbidity he
experienced as a result of the previous connective tissue graft.”
THE OUTCOME
This case illustrates the successful use of Geistlich Mucograft®, a xenogenic collagen matrix, for the treatment of multiple adjacent recession defects. Complete root coverage and an increase in the zone of keratinized tissue was obtained and a dento-gingival complex that is amenable to long-term health and stability was achieved. My patient was spared from the inevitable morbidities associated with a sub-epithelial connective tissue graft from a palatal donor site.

BIOBRIEF
Immediate Mandibular Molar Transition
THE SITUATION
The case here is typical enough, a failing mandibular molar with a vertical sub-osseous fracture. Traditionally, the replacement process can take three or more surgical exposures (extraction and regeneration), (implant placement), (second stage exposure) and more than a year of therapy.
THE RISK PROFILE
| Low Risk | Medium Risk | High Risk | |
|---|---|---|---|
| Patient’s health | Intact immune system Non-smoker | Light smoker | Impaired immune system |
| Patient’s esthetic requirements | Low | Medium | High |
| Height of smile line | Low | Medium | High |
| Gingival biotype | Thick – “low scalloped” | Medium – “medium scalloped” | Thin – “high scalloped” |
| Shape of dental crowns | Rectangular | Triangular | |
| Infection at implant sight | None | Chronic | Acute |
| Bone height at adjacent tooth site | ≤ 5 mm from contact point | 5.5 – 6.5 mm from contact point | ≥ 7 mm from contact point |
| Restorative status of adjacent tooth | Intact | Restored | |
| Width of tooth gap | 1 tooth (≥ 7 mm) | 1 tooth (≤ 7 mm) | 2 teeth or more |
| Soft-tissue anatomy | Intact | Compromised | |
| Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
Immediate molar replacement requires atraumatic removal of the fractured tooth, careful socket debridement and development of a channel for an ideally positioned implant. The implant then needs to be placed down in the bone channel with the implant platform positioned just below the socket walls. It needs to be stable. Channel deficiency augmentation is achieved with Geistlich Bio-Oss Collagen® which is covered with a collagen matrix, Geistlich Mucograft® with the edges tucked under the gingival margins and sealed over with tissue glue.
“The patient desires an implant placement for a fractured mandibular molar, as fast as possible.”
– Dr. Peter Hunt
THE OUTCOME
This single stage replacement protocol has proven to be simple, safe and highly effective providing the socket is fully degranulated and the implant is stable and not loaded in the early healing stages. It works well when a gingiva former is immediately placed into the implant instead of a cover screw, Geistlich Bio-Oss Collagen® is packed around the implant to fill the residual socket, then covered with a Geistlich Mucograft® and sutured. There is no need for flap advancement to cover over the socket.

BIOBRIEF
Ramal Bone Graft for Congenitally Missing Maxillary Lateral Incisor
THE SITUATION
An 18-year-old female presented with a congenitally missing tooth #10. The patient previously sought care by another provider and had undergone guided bone regeneration with allograft and subsequent implant placement with additional grafting at the time of implant placement. The implant ultimately failed and was removed prior to my initial consultation. An examination revealed maximal incisal opening, within normal limits, missing #10 with 6 mm ridge width. In addition there was a significant palpable cleft-like depression on the facial aspect of the ridge, adequate attached tissue but reduced vertical height in relation to adjacent dentition and attached tissue. Previous surgeries resulted in extensive fibrous tissue with scarring at site #10. Plan: A ramal bone graft is indicated at the congenitally missing site #10 with Geistlich Bio-Oss® and Geistlich Mucograft® matrix utilized for ridge augmentation prior to secondary implant placement.
THE RISK PROFILE
| Low Risk | Medium Risk | High Risk | |
|---|---|---|---|
| Patient’s health | Intact immune system Non-smoker | Light smoker | Impaired immune system |
| Patient’s esthetic requirements | Low | Medium | High |
| Height of smile line | Low | Medium | High |
| Gingival biotype | Thick – “low scalloped” | Medium – “medium scalloped” | Thin – “high scalloped” |
| Shape of dental crowns | Rectangular | Triangular | |
| Infection at implant sight | None | Chronic | Acute |
| Bone height at adjacent tooth site | ≤ 5 mm from contact point | 5.5 – 6.5 mm from contact point | ≥ 7 mm from contact point |
| Restorative status of adjacent tooth | Intact | Restored | |
| Width of tooth gap | 1 tooth (≥ 7 mm) | 1 tooth (≤ 7 mm) | 2 teeth or more |
| Soft-tissue anatomy | Intact | Compromised | |
| Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
The goals for this patient are to reconstruct the osseous foundation and provide a matrix for improvement with the overlying soft tissue. Specifically, a coordinated multidisciplinary plan was established with the restoring dentist, periodontist and oral surgeon. A plan for idealized anterior cosmetic prosthetic restoration was established. Sequencing of treatment was established. Surgical phase one included a ramal bone graft to site #10 and Essix type temporary prosthesis for immediate post-operative phase followed by a temporary Maryland bridge. Surgical phase two included implant placement and simultaneous crown lengthening and osteoplasty. This stage was done with immediate provisionalization.
“This is a young patient with a congenitally missing incisor that has high esthetic concerns and has had multiple failed surgical attempts that is now presenting for definitive management.”
THE OUTCOME
This case was dependent upon adequate hard-tissue reconstruction combined with soft-tissue manipulation to eliminate scar tissue and provide esthetic recontouring. Obtaining an adequate autogenous graft combined with Geistlich Bio-Oss® at the periphery of the onlay graft is essential for anterior-posterior and vertical augmentation. Utilizing a Geistlich Mucograft® matrix at the ridge crest to help contain the particulate graft and improve the soft-tissue profile for subsequent immediate provisionalization and re-contouring of the surrounding soft tissue played a significant role in the esthetic success.

Enhance Periodontal Phenotype with Geistlich Mucograft® for Soft Tissue Augmentation
THE SITUATION
A healthy, non-smoking, 37- year-old female presented for second stage surgery at implant sites #23 and #26. Limited keratinized tissue width and gingival thickness can be appreciated in the edentulous ridge, and the patient can be classified as having a thin periodontal phenotype. Additionally, the patient states she experiences sensitivity, and the tissue feels “tender” when brushing. The patient hopes to address her needs in a minimally invasive manner.
THE RISK PROFILE
| Low Risk | Medium Risk | High Risk | |
|---|---|---|---|
| Patient’s health | Intact immune system Non-smoker | Light smoker | Impaired immune system Heavy smoker |
| Patient’s esthetic requirements | Low | Medium | High |
| Height of smile line | Low | Medium | High |
| Gingival biotype | Thick – “low scalloped” | Medium – “medium scalloped” | Thin – “high scalloped” |
| Shape of dental crowns | Rectangular | Triangular | |
| Infection at implant sight | None | Chronic | Acute |
| Bone height at adjacent tooth site | ≤ 5 mm from contact point | 5.5 – 6.5 mm from contact point | ≥ 7 mm from contact point |
| Restorative status of adjacent tooth | Intact | Restored | |
| Width of tooth gap | 1 tooth (≥ 7 mm) | 1 tooth (≤ 7 mm) | 2 teeth or more |
| Soft-tissue anatomy | Intact | Compromised | |
| Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
The aim of treatment was to enhance the existing periodontal phenotype from that of one which is thin, with limited keratinized tissue, to one that is thick and maintains an adequate band of attached keratinized tissue. Geistlich Mucograft® was used in conjunction with a PRF membrane, in order to provide optimal wound healing, due to its chemotactic and angiogenic properties.
A viable option that allows for reduced patient morbidity, adequate functional necessity, and ideal esthetics.
THE OUTCOME
Dual application of platelet-rich fibrin (PRF) and a xenogenic collagen matrix, Geistlich Mucograft®, led to successful augmentation of the edentulous ridge. At one-year, the tissues appear healthy, and an increased keratinized tissue width and gingival thickness can be appreciated. By using this soft tissue alternative, the patient was able to avoid post-operative morbidity from a second surgical site, and the chief complaint was addressed.

Clinical Efficacy of Geistlich Mucograft® in Regeneration of Oral Mucosa Combined with the Surgical Treatment of Peri-implantitis in Implants with Lack of Keratinized Tissue
THE SITUATION
Adult patient, non-smoker and without relevant systemic history, attends to clinic referring peri-implant tissue inflammation, bleeding and brushing discomfort around her implant in the upper jaw. Clinically peri-implant pocket depth > 5 mm, bleeding and suppuration on probing were observed. Furthermore, the implant presented < 2 mm of keratinized mucosa and radiographic horizontal bone loss.

| Soft-tissue anatomy | Intact | Compromised | |
| Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
Intrasulcular incision was made and a mucosal partial thickness flap was raised. The recipient site was prepared by sharp disection in order to create a periosteal bed free of any muscle attachment. Peri-implant granulation tissue was removed and implantoplasty was performed. Finally, Geistlich Mucograft® was used to support the gain of keratinized tissue. Thus, the collagen matrix was sutured with the resulting flap apically at the base of the newly created vestibulum.
Absence of > 2 mm of keratinized mucosa was associated with peri-implant soft-tissue inflammation, bleeding and discomfort on brushing.
THE OUTCOME
After two years follow-up, the successful outcome can be observed in terms of clinical peri-implant parameters, gain of keratinized mucosa without significant graft shrinkage and stability of vertical position of the mucosal margin.
