OBJECTIVE: Newly developed non-invasive methods for replace a missing tooth and closing single-tooth gaps in the poster- ior region using resin composite are presented.
METHODS: Four different non-invasive methods and the technical procedures, materials and instruments used are presented in a case series. These include the direct intraoral insertion of composite (with and without individual shaping aids) and indirect restorations, which are fabricated conventionally or digitally and bonded.
RESULTS: The case series showed that all four methods can be used to replace single missing teeth in the posterior region, meeting current clinical requirements. Particular attention was paid to the design of the pontics, the dimension of the connector area, firm proximal contacts to the adjacent teeth, hygiene, and appearance of the non-prep bridges (NPBs). The advantages and disadvantages for both the direct and indirect techniques illustrated in this case series were com- pared in detail.
CONCLUSIONS: Several direct and indirect non-invasive methods for single-tooth replacement are available today. Although the evidence is still limited, there is a potential for frugal dental interventions with NPBs. Further experimental and clinical studies are necessary to demonstrate that they reliably meet quality requirements (including sufficient survival rates), satisfy the criteria of cost-effectiveness (compared to treatment alternatives) and that there is a demand from the population.

BACKGROUND: The rehabilitation of maxillectomy defects is a challenging endeavour that necessitates customizing the procedure for each patient. The successful treatment for these patients requires a combined conventional and contemporary treatment options. The high-tech prosthodontic treatment option for these defects and distal extension cases are combining fixed and removable partial dentures with precision/semi-precision attachments. It will enhance retention, stability, esthetics and functional ability of the prosthesis.
METHODS: Three post-Covid Mucormycosis patients reported after localised debridement and partial maxillectomy for definitive rehabilitation. For partial Maxillectomy patients, DMLS designed cast partial denture along with semi-precision attachments (Preci-vertix and OT strategy Rhein For patient with localized defect, DMLS designed cast partial denture was planned. For both patients the defect area was kept as hollow cavity (Closed or Open), in order to reduce the weight of the prosthesis.
CONCLUSIONS: The prosthodontic rehabilitation of these patient can be a simple and economical treatment options and it improves the stomatognathic functions and quality of life of the patient. The major hurdles during rehabilitation are retention and stability as there is no basal seat and hard tissue support. Hence, we tried a combined conventional and digital techniques in order to provide prosthesis with precise fit and accuracy as well as reducing the treatment time and visits of the patients.

Restoration of excessively worn dentition is a challenging treatment procedures. It requires efficient diagnosis and treatment plan. Hobo\'s techniques and Pankey Mann Schuyler\'s philosophy are widely used and documented for full mouth rehabilitation. We have reported the case of a 56-year- old male patient who presented with the severely worn dentition and had difficulty in chewing. To rehabilitate this case Hobo\'s twin stage technique had been adopted as it is based on scientific data and mathematical analysis for both disocclusion and anterior guidance thus reducing chair side time.

The choice for rehabilitation of an edentulous mandible by an implant supported overdenture is now the recommended minimally accepted option. This prosthesis has many advantages over conventional dentures and root or tooth supported overdentuers. We present a case of a failed conventional long span bridge which was treated satisfactorily using a four implant supported over denture and discuss our treatment option along with its advantages. This is a new and developing treatment option in our country.

Extensive mandibular resection commonly leads to a deviation of the mandible, facial disfigurement, and difficulty with speech and mastication. The rehabilitation of these patients is a prosthodontic challenge. This article presents the case of a 60-year-old man who sought prosthetic rehabilitation after a right segmental mandibulectomy. The prosthetic rehabilitation was planned in 2 phases. A palatal ramp was constructed, followed by a mandibular guiding flange. After 4 months, the patient\'s chewing ability, tongue movement, and facial esthetics were improved.

Gingival overgrowth is, among other things, a side effect of the administration of dihydropyridine antihypertensives, generally associated with irritant factors of marginal periodontium. This case refers to a patient, female, who developed a large gingival enlargement that has a combined etiology: the systemic medication with lercanidipina and the presence of dental bridges, which are incorrectly adjusted to the dental cervix. The treatment for this case, involved a complex local treatment (antimicrobial, surgical, endodontic and prosthetic) and the collaboration with a specialist cardiologist. Maintaining the normal gingival parameters in time depends on the possibility of changing the antihypertensive medication, the accuracy of the new dental bridges and the periodic monitoring of the patient.

The aim of this report is to present and discuss the clinical procedure of an implant-supported removable partial denture for a partially edentulous patient who exhibited a severely resorbed ridge and a collapsed vertical stop. The 67-year-old partially edentulous patient presented with a lack of vertical stop and an advanced transverse arch discrepancy. For the maxilla, an implant-supported removable partial denture was fabricated on bilateral distal implant abutments. The mandibular arch was restored with an implant-supported fixed partial denture, since it was expected to function more properly than a removable partial denture. This clinical report demonstrates a successful treatment approach to restore oral function and appearance for the patient.
