Introduction And Importance: Aliments such as congenital conditions, pathological, and iatrogenic circumstances may result in mandibular defects that can severely disturb the patients' oral health, functions (mastication, speech), aesthetics, and quality of life and present a rehabilitating challenge.
Case Presentation: we present a multidisciplinary treatment approach for three cases presented with mandibular resection as a consequence of cystic, benign, and malignant tumour eradication that were rehabilitated with immediately loaded fixed corticobasal implant-supported prostheses and a follow-up period of 5,5 and 4 years. The reported cases present with excellent implant survival, along with healthy peri-implant tissues, stable prostheses, enhanced speech, chewing ability, aesthetics, superior patient satisfaction, and improved overall self-esteem.
Aim: The aim of this retrospective study is to investigate the effect of corticobasal implant penetration in the nasal and maxillary sinuses on sinus health and implant survival rate in cases of severely atrophid ridges.
Materials And Methods: This retrospective study was conducted on thirty patients with 172 implants who underwent corticobasal implant treatment between 2014 and 2018. Implants were divided into two groups according to the penetration depths (Group A, <4 mm; Group B, 4 mm).
Introduction: Maxillofacial trauma is associated with severe loss of soft and hard tissues that lead to aesthetic and functional disfigurements, adverse psychological impacts on the patient's general and oral health, and decreased quality of life. Therefore, treatment of maxillofacial trauma is challenging.
Presentation Of Case: We present three patients with maxillofacial trauma owing to road traffic accidents that were rehabilitated by immediate use of loaded fixed corticobasal implant-supported prostheses with follow-up periods of 6, 5, and 7 years.
Introduction: Mandibular prognathism manifests as elongation of the mandible in the anteroposterior direction, resulting in a sunken appearance of the middle third of the face and sad look of the eyes. It adversely affects esthetics, function, and oral health, reducing the patients' self-esteem. It therefore presents a significant challenge.

Material And Methods: Three custom-made acrylic resin models of three tested implant systems (Straumann®, SIC Invent®, and Osstem®) with diverse coping geometrical designs were evaluated in simulated cases of two parallel and two nonparallel implants. The horizontal and vertical discrepancies were measured and analyzed.
Background: Implant protrusion into the nasal and maxillary sinuses presents a challenge in cases of severely resorbed maxillae.
Aim: The aim of this study was to evaluate the clinical and radiographic effects of BECES implant penetration depth into the nasal and maxillary sinuses.
Setting And Design: This was an observational study conducted in a tertiary institution.
Introduction: The prosthetic rehabilitation of mandibular defects owing to tumor resection is challenging, especially when the patient has undergone subsequent radiotherapy.
Presentation Of Case: A 46-year old male presented with a marginal mandibular resection. Following surgery, the patient received adjunctive radiation therapy with a total dose of 70 grays.
Introduction: Gunshot injuries to the oral maxillofacial region have serious aesthetic and functional consequences.
Presentation Of Case: A 32-year-old male patient presented with a marginal mandibular resection owing to a gunshot wound. A clinical examination revealed destroyed crowns in teeth 12, 11, and 21; extraction in teeth 13, 22, 24, 31, 32-45; a fracture in tooth 38; and severe pain.
The prosthetic rehabilitation of maxillary defect can be achieved successfully by using an implant-supported prosthesis. The use of remote bony areas such as the zygomatic bone in cases of large defects provides an innovative substitute for free vascularized osteocutaneous flaps and the solution to flap failures. This report describes the rehabilitation of a 22-year-old female with a subtotal maxillectomy using an immediately loaded basal implant-supported prosthesis.

Presentation Of Case: A 24-year-old woman presented with the skeletal and oral manifestations of CCD, including multiple poorly erupted and impacted teeth.
Background: An accurate impression is crucial to the long-term success of dental implants. This investigation evaluated the accuracy of the open and closed implant impression techniques in partially edentulous patients who received two adjacent implants.
Material And Methods: Forty patients received Osstem Implants (Osstem Implant System, Seoul, Korea).
Background: The outcome of the evaluation of impression techniques accuracy may improve the selection criteria for an ideal technique. The aim was to evaluate the accuracy of the open and closed tray techniques for implant impressions, in a partially edentulous maxilla, replaced with a three-unit fixed partial denture, as well as to assess the effect of implants parallelism on accuracy.
Material And Methods: This is an experimental in vitro study to evaluate impressions accuracy of a simulated area restored with an implant retained FPD, using the open and closed tray implant impression techniques.
