BIOBRIEF
The Buccal Pedicle Flap for Peri-Implant Soft Tissue Volume
THE SITUATION
Patient presented with a fistula buccal on tooth #9 associated with a chronic peri-apical lesion and external root resorption. Also tooth #8 showed a chronic peri-apical lesion. Her chief complaint was the misalignment of her teeth. The clinical situation revealed the presence of bleeding upon probing and generalized moderate periodontal disease (Stage II, Grade I) as well as multiple endodontic failures.

THE APPROACH
The aim of the treatment is to eradicate periodontal disease and restore esthetics and function. Treatment planning: non-surgical and surgical periodontal treatment, orthodontic alignment, extraction of both central incisors, immediate implant placement and Guided Bone Regeneration with Geistlich Bio-Oss®, peri-implant soft tissue boosting with a buccal pedicle flap and full ceramic CAD-CAM restorations.
THE OUTCOME
The final outcome at 8 weeks is showing pink esthetics as well as biomimetics and function. The use of the buccal pedicle flap allowed the increased volume of the peri-implant mucosa with a minimally invasive approach. The combination of Geistlich Fibro-Gide® and a buccal pedicle flap had the main advantage of reducing the morbidity generally associated with CT harvesting.

BIOBRIEF
Use of Geistlich Fibro-Gide® for Correction of Maxillary Anterior Soft Tissue Peri-implant Ridge Deficiencies
THE SITUATION
A 27-year-old female with congenitally missing maxillary lateral incisors was referred for implant placement. Following completion of orthodontics, a plan was developed to place dental implants at the #7 and #10 positions. Based on CBCT evaluation, alveolar ridge height and width was deemed sufficient for implant placement. Despite sufficient bone volume, facial ridge volume deficiencies were noted at both edentulous sites, requiring augmentation to allow for optimal esthetics.

Soft-tissue anatomy | Intact | Compromised | |
Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
The goal of treatment was to replace missing maxillary lateral incisors with dental implants, while providing an esthetic result with predictable and minimally invasive techniques. Employing a surgical guide for implant placement, implants were placed in precise 3-dimentional positions. The use of xenograft biomaterials (Geistlich Fibro-Gide®) allowed for the augmentation of gingival biotype and elimination of the buccal ridge deficiencies while avoiding the harvesting of autogenous tissue.
THE OUTCOME
The presented case involves a female patient with congenitally missing maxillary lateral incisors and soft tissue ridge deficiencies. Implants were placed and a volume-stable collagen matrix Geistlich Fibro-Gide® was placed to provide labial soft tissue volume. The tissue emergence was then developed with the use of provisional restorations, one placed at the time of surgery, the other following implant integration. The implants were restored with gingival tissue transformed to mimic convex root emergence.

BIOBRIEF
Phenotype Conversion Using Geistlich Fibro-Gide® for Immediate Implants in the Esthetic Zone
THE SITUATION
A healthy non-smoking 50-year-old female patient who desires a single tooth solution to replace a non-restorable tooth, #12. A root fracture at the level of the palatal post was diagnosed in a root canaled tooth. Maintaining esthetics of the adjacent teeth is important as they are also restored with single full coverage porcelain crowns. Lastly, treatment time reduction and a minimally invasive surgical technique are desired by the patient for reduced downtime and post-operative morbidity.

Facial Bone Wall Phenotype: High Risk (<1mm)
Esthetic Risk Profile (ERP) = Medium (summary of above)
THE APPROACH
A minimally invasive surgical removal of tooth #12 with maintenance of the buccal plate and leaving a 3mm buccal gap. The implant will be placed one mm below the level of the intact buccal plate with an anatomically correct surgical guide template to provide for a screw-retained solution. The gap will be filled with Geistlich Bio-Oss Collagen® to maintain the bone buccal to the implant, and a palate free approach utilizing Geistlich Fibro-Gide® for soft tissue thickening to accomplish “phenotype conversion.” The long-term surgical goal is >2-3mm thickness of both hard and soft tissue buccal to the implant.
THE OUTCOME
Minimally invasive surgery for buccal wall maintenance, virtually planning the buccal gap and implant width, using a xenograft in the buccal gap with phenotype conversion using a volume stable collagen matrix in conjuction with immediate contour management, allows for the best chance for papillae fill interproximally and maintenance of the mid-buccal gingival margin long-term.

BIOBRIEF
Soft-Tissue Augmentation in the Esthetic Zone
THE SITUATION
A young male patient was referred to the clinic with a missing central incisor, #9 following trauma. An implant was placed and the patient was referred for an implant-born reconstruction. The patient does not smoke and drinks occasionally. Upon a clinical examination, extensive horizontal and vertical contour deficiencies are present prior to abutment connection.

Soft-tissue anatomy | Intact | Compromised | |
Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
THE APPROACH
The compromized situation with a horizontal and vertical hard and soft-tissue deficit required a soft-tissue volume grafting procedure. A buccal split-thickness flap was prepared and Geistlich Fibro-Gide® shaped and placed. Primary wound closure was obtained. Abutment connection was performed after 8 weeks and the emergence profile created with a provisional reconstruction. The final reconstruction was placed at 3 months.
THE OUTCOME
The outcome of the case was very pleasing having fulfilled the patient’s expectations in terms of esthetics and function. The tissues are healthy and volume was obtained through the grafting procedure to match the contour of the neighboring natural tooth.

BIOBRIEF
Root Coverage for Multiple Adjacent Teeth in the Maxilla with Geistlich Fibro-Gide® 1.5-Year Follow-Up
THE SITUATION
The patient is a healthy, 60-year-old female who presented to our clinic with a chief complaint of progressive gum recession which had led to compromised esthetics and sensitivity involving the maxillary left lateral incisor (#10), canine (#11), and first bicuspid (#12) teeth. The teeth in question had 3-4 mm of gingival recession on the buccal surface with a sufficient zone of keratinized gingiva. These teeth also had obvious cervical abrasion.

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 |
Severity of recession – mild to moderate
Amount of keratinized gingiva – 2 mm or greater for all teeth involved
THE APPROACH
Treatment goals for this case were to obtain complete root coverage, increase soft tissue thickness, and reduce/eliminate cervical sensitivity. A split-thickness envelope flap approach was used. Geistlich Fibro-Gide® was then trimmed, hydrated with saline, and placed over the exposed root surfaces. The flap was coronally advanced in a tension-free manner to completely cover the biomaterial and exposed root surfaces.
THE OUTCOME
This case nicely shows that the result following root coverage surgery to treat multiple adjacent teeth using a volume-stable collagen matrix is comparable to that seen with autologous connective tissue. At 1.5 years, there is continued stability of the treated site. The tissue appears healthy and firm. The patient‘s chief complaints of esthetics and sensitivity have been addressed and the patient is maintaining excellent oral hygiene and home care.

BIOBRIEF
Prosthetically Guided Regeneration (PGR) in the Posterior Maxilla
THE SITUATION
The 60-year-old female patient’s chief complaint was represented by unsatisfactory esthetics and function, related to loss of multiple maxillary teeth. Her request focused on improving esthetics and function by means of a fixed reconstruction.
The patient presented five residual anterior maxillary teeth (from 6 to 10) that could be maintained. After preliminary periodontal diagnosis and treatment, specific diagnostic steps for implant treatment demonstrated inadequate bone volume for implant placement.

THE APPROACH
Bi-lateral sinus lift with Geistlich Bio-Oss Pen® and horizontal bone augmentation with a 1:1 mix of autogenous bone and Geistlich Bio-Oss® were performed six months prior to implant placement, following a Prosthetically Guided Regenerative (PGR) approach. The augmented sites were protected with Geistlich Bio-Gide® stabilized with titanium pins. The template utilized for radiographic diagnosis and GBR was then used to guide the implants’ placement.
THE OUTCOME
After a healing period of six months, adequate bone volume was achieved for the placement of five implants. Geistlich Fibro-Gide® was also used to optimize soft tissue volume at the buccal aspect of implants.
Implants were early loaded with a temporary screw-retained fixed prostheses six weeks after placement. The final prosthetic reconstruction included ceramic veneers of the frontal residual teeth and zirconium-ceramic screw-retained fixed prostheses on implants.

BIOBRIEF
Avoiding Post-Implant Placement and Long Term Crestal Bone Resorption by Thickening Vertical Soft Tissue
THE SITUATION
Our patient is a 60-year-old caucasian male that had just finished a large ridge augmentation in the area of #4 and #5. We used the sausage technique for the ridge augmentation and yielded excellent bone volume in this area. However, as we began the 2nd stage implant placement procedure, we noticed, as is frequently seen following a large ridge augmentation, very thin vertical soft tissue over the crest of the bone. We know that inadequate soft tissue thickness will lead to compromised vasculature and transfer of oxygen and nutrients to the bone which can absolutely lead to a loss of crestal bone surrounding the implants.
THE RISK PROFILE

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” |
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 |
Note: Bone was augmented prior to this case report due to a severe horizontal defect.
THE APPROACH
Our goal here is to create increased vertical soft tissue thickness over the crest of the implant site. Following implant placement and placement of the cover screws, we used Geistlich Fibro-Gide® over the implants and then layed it over the crest and buccal aspect. Following the placement of Geistlich Fibro-Gide®, we gently released the full thickness flap so that we can achieve tension-free primary closure over the site.
THE OUTCOME
The soft tissue that will now surround the implant site is thick and healthy due to the use of Geistlich Fibro-Gide® at the time of implant placement. This is a simple technique and only requires a minimal amount of flap release to achieve tension-free primary closure over the site. The results are phenomenal and will be beneficial for the stability of the crestal bone surrounding the implants for years to come.

BIOBRIEF
A Regenerative Approach to Peri-implantitis
THE SITUATION
A 55-year-old man was referred to me by his general dentist. Upon initial clinical and radiographic findings, failing implant #9 showed signs of peri-implantitis that included BoP, Suppuration, 9+mm PD and radiographic bone loss affecting both the implant and the natural adjacent tooth. Patient stated that although his gums bleed, he does not have any pain. Gingival erythema was also found.

Soft-tissue anatomy | Intact | Compromised | |
Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |
Note: Peri-implantitis on implant #9 migrating to the mesial portion of root #8
THE APPROACH
The clinical goals were to eliminate the peri-implant infection, restore hard and soft-tissues and have long-term success. The technique utilized was a systematic regenerative approach to eliminate the underlying cause of the peri-implantitis infection and restore hard and soft-tissues to prior health.
THE OUTCOME
My observation at the 1.5 year follow-up shows the elimination of peri-implantitis and complete peri-implant health was achieved showing a reduction in BOP, PD and most importantly soft tissue thickness stability. Radiographically, crestal bone shows no signs of progressive pathological loss and has maintained adequate volume.
