“…29 A plausible explanation for this observation is that wider DI would be more stable than narrower ones because they can potentially engage a larger amount of the osseo-integrated interface. On the other hand, other studies, 37,38 found no difference regarding the effect of DI diameter on secondary stability ISQ values.…”

A 33-year-old woman presented with dissatisfaction with the appearance of her external nasal contour. On physical examination, a depression over the nasal dorsum and irregularities in the surrounding skin were observed. She had undergone rhinoplasty through a closed approach 14 years prior and had no history of trauma since. The implant material that was previously inserted wobbled on the nasal dorsum and was palpable on the nasal tip. On lateral radiography, we found a previously inserted L-shaped implant in the supratip area. The implant was completely fractured, mimicking a nasal bone fracture (Fig. 1A). We decided to perform revision rhinoplasty under local anesthesia with intravenous sedation. After making bilateral alar marginal and inverted V transcolumellar incisions, we observed the fractured caudal part of the L-shaped silicone implant in the nasal tip area (Fig. 1B). It was separated from the cephalic part of the L-shaped silicone, which was located in the nasal dorsum (Fig. 1C). It was encapsulated with surrounding fibrous tissue, and the alar cartilage was carefully separated from the capsule. We reinforced the nasal support with 2-layered struts and performed tip augmentation with a 3-layered onlay graft using the septal cartilage. We created a pocket through the subperiosteal plane and inserted a new I-shaped silastic implant for dorsal augmentation. The patient's surgical outcome was satisfactory, and the depressed nasal dorsum and skin irregularity were corrected.

“…Similarly, Vasilena Ivanova et al [33] reported a positive correlation between secondary stability and bone density (r = 0.498). They underwent a socket preservation procedure with allograft or platelet-rich fibrin (PRF) and after 4 months, a total of 90 implants were placed.…”

The aim of this study was to examine the formation and density of new bone around dental implants inserted simultaneously after grafted versus non-grafted maxillary sinus floor augmentation and to correlate secondary implant stability to bone density. Twenty patients requiring the placement of implants in the posterior maxilla with deficient bone height were recruited for the study. Patients were randomly assigned to either group. The formation and density of new bone were evaluated using Cone-Beam Computed Tomography, performed postoperatively and after 6 months. Pearson coefficient was used to correlate bone density and secondary implant stability in both groups. All implants achieved adequate primary stability and were successfully loaded. Both groups showed comparable secondary stability with a mean of (77.9 ± 3.9) for the grafted and (74.8 ± 5.6) for the non-grafted group. Bone density values were (973.6 ±142.5) and (443.7 ± 97.8), and bone height gain was (6.6 ± 0.5) and (6 ± 0.5) for the grafted and the non-grafted groups respectively, with the grafted group showing significantly higher values. Secondary stability showed a significant positive linear correlation with bone density in the grafted group (r = 0.549 at p ≤ 0.05). In conclusion, Sinus floor elevation with and without grafting is considered an acceptable and successful procedure with simultaneous implants placement. Furthermore, higher density values in the grafted sinuses resulted in higher secondary stability.

“…In our research, the grafting material was completely absorbable, so it was not affecting the measurements [50]. Moreover, numerous papers backing a correlation between CBCT-derived bone GVs and primary and secondary implant stability, which is a clinically significant parameter, were published [51][52][53][54][55]. Nevertheless, the literature data on those correlations are ambiguous, which has to be taken into consideration when drawing conclusions [50].…”

The Assessment of the Usefulness of Platelet-Rich Fibrin in the Healing Process Bone Resorption

et al. 2022

The main subject of this research was the use of PRF in dental surgery aimed at preventing changes in alveolar height and width after tooth extraction. Due to the large growth factor content, it seems to be particularly useful in bone loss management starting from the simplest loss occurring after tooth extraction through loss resulting from tooth resection ending with loss caused by large bone cysts. The study was performed on 50 patients. The extraction of two maxillary or mandibular homonymous teeth was carried out in each patient, where PRF was placed in one alveolus while the other alveolus was left empty. Then, the alveoli were surgically managed with a split flap technique. On the extraction day, after 10 days, and after 6 months, the alveolar process was measured, soft tissues healing was assessed, and imaging examinations were analyzed. It was proved that the healing of soft tissues in the PRF group was better. In the PRF group after 6 months from surgery, the newly formed bone had higher grayscale values in volumetric tomography (CBCT). Moreover, the reduced atrophy of the alveolar process at the site of the extracted tooth was proved in this study.
