The results of the clinical study proves the reliability and low comorbidity of autologous bone grafts in preprosthetic alveolar ridge reconstructions prior to implant insertion.

Data on risk factors based on the original examination and documentation are difficult to assess the adverse effects of variable factors on the surgical prognosis because of the multifactorial genesis of surgical complications [73]. Factors such as gender, age, or smoking habit could be associated with postoperative complications after two-stage dentoalveolar reconstruction with autologous bone gr...
The results of the present study have to take into account the absence of a control group with patients undergoing bone augmentation procedures with bone substitutes (allogen, alloplastic, exogen). Without a comparative group of grafting surgeries using alternative bone material, only limited statements can be made.
However, the excellent surgical outcome of autologous surgical methods providing ...
The use of autologous bone in this study has shown excellent graft survival and success rate (95.6%). This is equal to the results from the studies on implants inserted in reconstructed sites [6, 8, 24]. The early implant survival rate of 99.7% found in the present material is very high comparable to that in the previous systematic reviews after staged horizontal ridge augmentation [9, 10, 22, 62,...
Of the sinus floor elevations performed in this study, 84.8% were defined absolutely successful. Only two of our 72 patients having sinus lift operations could not finally be treated with dental implants. These results are comparable to other studies considering the sinus graft to be a safe treatment modality with few complications [6, 8, 51,52,53]. Raghoebar et al. reported incidences of sinus co...
Postoperative morbidity after mandibular bone harvesting procedures was reported to be mainly related to temporary or permanent neural disturbances involving the inferior alveolar nerve and its branches [19]. In this study, only the incidence of the temporary hypoesthesia of the mandibular and lingual nerve after harvesting from the retromolar area could be detected. It was 10.4 and 2.8%, respecti...
Systematic reviews have failed to find evidence that one particular grafting technique is superior to others [10]. Intraoral bone grafts from the mandibular symphysis, mandibular ramus, and maxillary tuberosity provide a good treatment modality for ridge augmentation, and the amount of bone available for harvesting is sufficient for defects up to the width of three teeth [42]. Harvesting of retrom...
Several grafting procedures have been described to create sufficient volume of bone for implant placement [8, 9]. Autologous bone grafts can be harvested by an intraoral approach (mandibular ramus, mandibular symphysis, zygomatic buttress) or from distant sites (iliac crest, calvaria, and etc.) [17, 36, 37]. However, bone harvesting potentially causes donor site morbidity which is a major issue fo...
The average healing period until implant placement after bone harvesting was 4.53 months. Initially, 546 implants in 279 patients were planned. After the healing period, it was possible to place 525 implants in 436 successfully augmented areas in 259 patients. Three hundred implants were inserted in the maxilla and 225 in the mandible. The remaining 21 implants planned for 20 patients could not b...
Regarding intraoperative complications, all sinus membrane perforations were covered with a resorbable collagen membrane (Bio-Gide®, Geistlich Biomaterials, Baden-Baden, Germany) which applied as sealant to overlap the site of perforation prior to insertion of the graft material. These patients were advised to avoid physical stress, blowing their noses, or sneezing for a period of 3 weeks, and n...
No permanent damage to any trigeminal nerves was evident in any of our entire cohort. All cases of postoperative hypoesthesia of the mental, lingual, or infraorbital nerve were just a temporary nature. At the time of implant surgery, none of these patients reported any persisting neural disturbances (Fig. 4).
In eleven patients, hypoesthesia of the mental area was mentioned, and three of them al...
Thirty-eight patients underwent a total of 116 augmentation procedures harvesting from the iliac crest. In 20 patients, a bone graft augmentation of the maxilla and the mandible in combination with bilateral sinus floor augmentations was performed. Eighteen patients had augmentations only in the maxilla, involving bone grafting and sinus lift elevations. Totally, 76 sinus lifts with bone material ...
In six patients, a partial graft resorption was detected at the time of implantation and an additional simultaneous augmentation with bone chips harvested with the Safescraper device (C.G.M. S.p.A., Divisione Medicale META, Italy) was then necessary in order to ensure the osseointegration of the implants. Two out of these six cases had grafts from the crista zygomatico-alveolaris, two from the ram...
A total of 112 sinus floor elevations were performed. In all of the cases, implants were inserted in a two-stage procedure. The donor site for harvesting the bone for the sinus elevations was in 76 procedures in the iliac crest area, and in 36 procedures, the bone was harvested with a bone scraper device from the lateral sinus wall at the site of sinus lifting.
The distribution and number of tran...
Two hundred seventy-nine patients—250 men and 29 women—underwent 456 augmentation procedures involving autologous bone grafts prior to implant placement. The patients ranged in age from 18.5 to 71.5 years (average 43.1 years) at the moment of augmentation surgery.
Of those patients, 162 (58.1%) were younger than 40 years of age and 117 (41.9%) were older than 40 years of age. Caries or pe...
Early and late implant loss was documented in this study, defining the clinical success of osseointegration. Early implant failures were assessed before the acquisition of osseointegration, i.e., before the placement of prosthodontic restorations. Early implant failure could occur from the time of placement, during the healing phase and before abutment connection. The implant inserted after re-aug...

In addition to the bone already gained with the bone scraper device from the sinus wall during the antrostomy, bone was harvested with the same device from the maxillary buccal buttress, if more volume was needed. By taking this approach, the collection of enough bone for the augmentation of at least two implantation sites was feasible with a mean surgical time of 5 to 10 min for harvesting. In c...
Grafting from the iliac crest was always performed under general anesthesia in a two-team approach. The iliac crest was exposed and autogenous grafts from the anterosuperior inner edge of the iliac wing were harvested with an oscillating saw and/or a chisel, keeping a safe distance of around 2 cm from the anterosuperior iliac spine. After harvesting the bone grafts, the corticocancellous bone blo...
A standardized two-stage surgical protocol was used, and all sites were treated in a similar fashion. In the first intervention, a bone block harvested from the donor site was fixed with osteosynthesis titanium screws to the recipient site as an onlay graft to achieve a horizontal and/or vertical enlargement of the alveolar ridge. Placement of the bone graft was always guided by an augmentation te...
For this retrospective cohort study, we reviewed the records of all patients without exclusion criteria who were referred to the department of oral and plastic maxillofacial surgery at the military hospital of Ulm, Germany, between January 2009 and December 2011 for alveolar ridge augmentations prior to implant insertions using autologous bone grafts harvested from different donor sites and unilat...
In our military outpatient center exclusively, autologous bone transplantations harvested from different donor sites were used intraorally (crista zygomatico-alveolaris, ramus mandible, symphysis mandible, anterior sinus wall) and extraorally (iliac crest) to reconstruct severe horizontal and/or vertical alveolar ridge atrophy prior to implant placement. The aim of this study was to assess the cli...
Although the iliac crest is most often used in jaw reconstruction, a significant bone resorption has been mentioned [12]. This disadvantage, and the fact that dental implants do not always require a large amount of bone, has increased the use of autologous block bone grafts from intraoral sources [13]. Bone grafts from intraoral donor sites offer several benefits like surgical accessibility, proxi...
Oral implantation has a significant role in the rehabilitation of patients. Bone reconstruction techniques have been advanced in order to optimize the esthetic and functional outcome.

This review demonstrates the predictability of autologous bone material in alveolar ridge reconstructions prior to implant insertion, independent from donor and recipient site including even autologous bone chips for sinus elevation.
