Synthetic calcium phosphates have been tested in randomised trials of sinus augmentation and ridge preservation but rarely in ridge augmentation. To our knowledge, the augmented volume of biphasic calcium phosphate (BCP) mixed with autogenous bone has not been measured clinically in non-contained ridge defects. We grafted four such maxillary defects with BCP (RESORBA Synthetic Bone, hydroxyapatite/β-tricalcium phosphate 60/40; S1, S2) or porcine xenogeneic mineral (RESORBA Xenogenic Bone Graft; X1, X2), each mixed 50:50 with scraper-harvested autogenous chips, under a native collagen membrane (PARASORB RESODONT Forte). Cone-beam computed tomography volumetry gave the net radiodense volume (new bone and residual graft) in a fixed 10 × 10 mm window, with measurement envelopes over analysis choices. All four sites healed uneventfully and received implants, with the graft (S1, X1) or at re-entry (S2, X2), S2 with 2 mm of buccal hard tissue despite loose particles outside the contour. All were uneventful for 13–65 months after grafting, apart from one resolved sinus tract in X1. Volumes (mm³, envelopes in brackets) were 99.7 (91.8–112.3) in S1 and 137.0 (127.6–150.8) in X1, their envelopes overlapping before the post hoc changes, and 95.4 (82.3–99.5) in S2 and 267.1 (261.4–272.3) in X2, apart before and after them. As each volume difference is also one between patients and sites, none is attributed to the substitute.

Background: Oral lipomas are uncommon benign tumors composed of mature adipocytes, accounting for roughly 1% of benign intraoral lesions. Common predilection sites are buccal mucosa, lips, and tongue, presenting as slow-growing, nodular masses, often with a yellow hue. As the size of most lesions does not exceed 10 mm, particularly larger lipomas may be misdiagnosed. We present two cases of large oral lipomas. Case reports: Case 1: A 58-year-old male with a painless, sessile nodular mass of approximately 2.5 cm in the left cheek, increasing in size and causing discomfort during mastication. After excision, histopathology revealed mature adipocytes with delicate fibrous septa. Case 2: A 47-year-old female with a tender yellow growth of approximately 2 cm in her lower lip, increasing in size and causing aesthetic problems with functional discomfort. After sharp dissection, the specimen presented acanthotic and parakeratotic epithelium with adipocytic tumorous tissue, permeated by collagenous cords. Conclusions: Oral lipomas are uncommon, mostly asymptomatic benign lesions. Mostly found in the buccal mucosa and lower lip, they can mimic more common growths. When located superficially, a conservative surgical excision leads to resolution with rare recurrences. Histopathological inspection is necessary to confirm the benign nature of the lesion.

Background/Objectives: This case report describes a rare case of bilateral coronoid hyperplasia (CPH) with suspected Jacob’s disease in a young female patient, managed by endoscopically assisted coronoidectomy, and provides quantitative oral-health-related quality of life (OHRQoL) and pain outcomes. Methods: An 18-year-old female with severely restricted mouth opening underwent bilateral endoscopically assisted intraoral coronoidectomy. OHRQoL and pain were assessed with the Oral Health Impact Profile 14 (OHIP-CRO14) and a 100 mm visual analogue scale (VAS) preoperatively, daily for seven postoperative days, and at one year. Results: Maximum mouth opening improved from 8 mm to 35 mm at nine months (+338%). OHIP-14 total scores remained within a “poor”-to-“moderate” impact and low quality of life from the preoperative value (38) throughout the postoperative week (31–38) and decreased to 14 at one year (−63%; “good” impact, very high quality of life). Psychological disability and psychological discomfort were the most affected domains. VAS scores rose from 36 preoperatively, peaked at 55 on day 2, fluctuated as mild pain (27–44), and resolved at one year. Conclusions: Endoscopically assisted intraoral coronoidectomy restored functional mouth opening and produced clinically meaningful improvements in pain and OHRQoL, with the largest gains in psychological domains. To the authors’ knowledge, this is the first case report providing quantified, domain-resolved OHRQoL outcomes after coronoidectomy.
