Fixed Partial Denture Treatment With Mini Dental Implants

Abstract Objectives The aim of the present study was to investigate whether peri-implant clinical parameters (modified plaque index (mPI), bleeding and/or suppuration on probing (B/SOP)) and local factors (type of prostheses, screw emergence, platform diameter, and abutment angulation) might contribute to the development of additional bone loss and peri-implantitis around dental implants. Materials and methods Two hundred seventy-seven external hex connection implants placed in the posterior maxilla of 124 patients were retrospectively evaluated. They were divided into two groups: physiologic bone loss < 2 mm (PBL) or additional bone loss ≥ 2 mm (ABL). GEE logistic regression was applied to evaluate the influence of type of prostheses (implant-supported single crown (ISSC), fixed partial denture (ISFPD), and full denture (ISFD)) and clinical parameters (mPI and S/BOP) on bone loss. Results Among the 277 implants, 159 (57.4%) presented PBL and 118 (42.6%) presented ABL. Within the ABL group, 20.6% implants were diagnosed with peri-implantitis. mPI significantly correlated with the type of prosthesis and the highest value of mPI (index = 3) was observed in ISFD (23.8%). Moreover, peri-implantitis was more frequently associated with ISFD (32.79%) than ISSC and ISFDP (13.79% and 13.48, respectively) Conclusions ISFD in the posterior maxilla presented high rates of ABL and showed a higher prevalence of peri-implantitis. None of the local factors seemed to contribute to the development of these conditions. Further investigations are needed to prospectively support the results of the present study. Clinical relevance Patients rehabilitated with ISFD should be carefully monitored and have more frequent maintenance visits to prevent or control peri-implant bone loss.

Edentulous Mandible

ABSTRACT Aim The aim of this study was to evaluate the stress developed in the bar connecting implants and in the mandible as a result of the elastic deformation of the mandible during mouth opening when using a finite element method (FEM). Materials and methods A three-dimensional model of an edentulous mandible was generated based on the computer tomography (CT) data of a patient. Two cylindrical implants (diameter 4.3 mm, length 13 mm) were inserted in the area of the mandibular canine, premolar and molar in the mandibular model. Implants were connected with a rigid bar (width 2 mm, height 3 mm), and mouth opening was simulated on the threedimensional (3D) model. The location and magnitude of maximum von Misess stress that occurred in the mandible and in the bar were estimated. Results The highest stress level in the mandible (4.5 GPa) and in the splint (32 GPa) was measured in the longest fixed partial denture with the implants in the mandibular left canine and left second molar position. The maximum stress in the bone was measured distal to the splinted implants. Conclusion Since, great distance between splinted implants caused high stress during mouth opening, due to mandibular deformation, the use of a short span fixed partial denture supported by implants in the molar region of the edentulous mandible is probably more advantageous.

Craniofacial Syndromes

AbstractMultiple dental impactions not associated with craniofacial syndromes are a rare condition and present the dentist with a therapeutic challenge when it comes to performing surgical/restorative treatments in adult patients. This case report describes a geriatric patient with multiple impacted teeth restored by means of two different protocols. In the second quadrant, an impacted tooth was extracted followed by regeneration and placement of an implant. In the third quadrant, implants were placed though impacted teeth for restoration with a fixed partial prosthesis. Placing dental implants through impacted teeth may offer a possible therapeutic option for implant-supported restorations in middle-aged or elderly patients, for whom surgery and orthodontic traction are not possible, and/or patients who refuse to undergo more invasive extraction surgery.

Denture Treatment

Aims: The aim of this study is to evaluate the rugae pattern changes (rugae number, length, shape, direction, and unification) in completely edentulous patients treated with complete denture. Materials and Methods: A total of 100 subjects were selected for the study. The experimental group comprised 60 participants (30 males and 30 females) who had undergone complete denture treatment and the control group comprised 40 participants (20 males and 20 females) who were dentulous and patients with fixed partial denture treatment. Mucostatic maxillary alginate impressions were made for all the subjects, and casts were poured with gypsum. Patients were recalled at the regular intervals of 1, 6, and 18 months after the treatment. During those recalls, the same impression procedure was made, and all the palatal rugaes were observed for number, length, shape, direction, and unifications under magnifying lens. Changes in the palatal rugae were statistically analyzed using the unpaired t‑test. Results: A gradual decrease in the length was observed in primary, secondary, and fragmentary rugae for the experimental group after denture wearing (Group 1). Statistically, the change was significant (P < 0.001) in primary rugae only. A slight change in rugae shape was also observed in the experimental group after 18 months period of denture wearing which is statistically insignificant (P > 0.05). Conclusions: Significant decrease in primary rugae length in complete denture wearers was due to sustained mechanical stress posed by the dentures on palatal rugae. The other parameters such as rugae number, direction, and unification remained constant throughout the study. Palatal rugae analysis may not be helpful for human identification in complete denture wearers. Nevertheless, palatal rugae may serve as an adjuvant to other techniques such as DNA analysis and finger prints in forensic investigations.
