“…For this, the fragment might be stored in the abdominal wall and then frozen in storage [1]. However, such techniques may have the disadvantages such as resorption of the bone graft or infection [4, 7]. Patients undergoing decompressive craniotomy can develop the “syndrome of the trephined,” with symptoms such as dizziness, anxiety, irritability, and intolerance to noise or vibration.…”

“…However, disadvantages include the risk of bone graft resorption, insufficient availability of the required quantity of bone, or the refusal of the patient to approach another surgical site for harvest of the bone graft due to the associated morbidity. These factors would tend to favor the use of an alloplastic material [2, 3, 5–7, 9]. Advantages of alloplastic materials include ready availability, resistance to resorption, easy handling and workability during surgical procedures, and long-term stable and satisfactory cosmetic results [3, 5, 7].…”

“…Autogenous bone grafting remains the first choice for reconstruction of bone defects, but often the patient refuses a second surgical site with resultant morbidity to obtain bone or the amount of bone available is insufficient; for such cases, alloplastic implant materials are used [3, 6]. Currently, the most widely used alloplastic material for these craniomaxillofacial reconstructions is polymethyl methacrylate (PMMA), a biocompatible and nondegradable acrylic resin-based implant, which can be fabricated prior to surgery, with the advantages of reduced surgical time, the use of a simple technique, and excellent long-term aesthetic results [3, 5, 7]. …”

Craniofacial defects represent alterations in the anatomy and morphology of the cranial vault and the facial bones that potentially affect an individual's psychological and social well-being. Although a variety of techniques and restorative procedures have been described for the reconstruction of the affected area, polymethyl methacrylate (PMMA), a biocompatible and nondegradable acrylic resin-based implant, is the most widely used alloplastic material for such craniomaxillofacial reconstruction. The aim of this study was to describe a technique for aesthetic and functional preoperative customized reconstruction of craniofacial bone defects from a small series of patients offered by the Brazilian public health system. Three adult male patients attended consultation with chief complaints directly related to their individual craniofacial bone defects. With the aid of multislice computed tomography scans and subsequent fabrication of the three-dimensional craniofacial prototype, custom-made PMMA implants were fabricated preoperatively. Under general anesthesia, with access to the craniofacial defects with a coronal approach, the PMMA implants were adapted and fixated to the facial skeleton with titanium plates and screws. Postoperative evaluation demonstrated uneventful recovery and an excellent aesthetic result. Customized prefabricated PMMA implants manufactured over the rapid prototyping models proved to be effective and feasible.

“…The decision regarding cranioplasty must be influenced by the patient's age, prognosis, activity level and the specific condition of the scalp and the calvarium. There are two basic methods for reconstruction viz (a) Osteo-plastic reconstruction [2,3] and (b) restoration with alloplastic implants [4,5]. To achieve a successful result, adequate vascularity of the scalp flap, presence of dura, presence of outer layer of periosteum and absence of infection are important factors.…”

“…It can be used either as a heat cured preformed implant or cold curing form. A preformed poly methyl methacrylate implant is preferred as there is no heat on polymerization and no excess liquid monomer which might irritate and damage the underlying structures [4]. This implant is radiolucent and non-carcinogenic.…”

Background: The aim of this study was to evaluate the efficacy of heat cured 'poly methyl methacrylate resin prosthesis and to assess the acceptability of the indigenously manufactured titanium mini bone plate and screws in patients treated for repair of cranial defects. Methods: 17 patients with cranial defect were treated for reconstruction of the skull defect with two types of implants i.e. Acrylic resin plate prosthesis and titanium minibone plates, either in combination or singularly. In these cases, the skull defects resulted from trauma (88.23%) or due to ablative tumour surgery (11.96%). Acrylic implant was used in 12 cases (70.85%), titanium plates and screws in 2 cases (11.76%) and a combination of both of the above in 3 cases (17.64). Results: The primary reconstruction was carried out in 2 cases (11.96%) and secondary reconstruction was done in 15 cases (88.23%). Majority of the cases underwent secondary reconstruction because of the initial surgical emergency requiring quick debulking and closure. In 2 cases where primary reconstruction was done, the second surgery could be avoided with gratifying results. Conclusion: 70.85% underwent reconstruction with polymethyl methacrylate resin prosthesis and in the rest either titanium plates were used singly or in combination. Only in one patient, there was rejection of the implant due to infection. In 94% cases the graft was well taken up with excellent results. MJAFI 2005; 61 : 36-40

Poly(methyl methacrylate) (PMMA)‐based bone cements (BCs) can be defined as a family of materials that consist of powder and liquid phases which after mixing form a plastic paste that can self‐set once implanted in the human body. PMMA‐based BCs are easily molded and adapted to complex bone cavities or used in orthodontic applications to restore dental damage. The main advantages of the use of cement are the excellent primary fixation between bone and implant and, therefore, the faster recovery of the patient. Despite the initial success rate of implant fixation with BCs, they have some disadvantages such as local tissue damage due to exothermic polymerization reactions, mechanical mismatch between native bone and cement, lack of bone regeneration and bioactivity and poor mechanical properties which may cause the failure of the BCs. BCs are still considered as a top option for bone repair. Due to the disadvantages highlighted, research has focused on alternative materials used with PMMA‐based BCs. This review aims to critically review the BCs and emerging materials used in combination with PMMA‐based BCs. These materials include titania, apatite–wollastonite (A‐W), glass ceramic (GC) and hydroxyapatite (HA). The review discusses the properties of these materials and their pathway to clinical study. Among the various kinds of reinforcement, HA has been extensively used. So, in this review, we compare the effects of HA as reinforcement in PMMA‐based BCs. Upcoming study of PMMA‐based BCs should concentrate on trialing combinations of these reinforcing agents as this might improve beneficial characteristics. © 2020 Society of Industrial Chemistry
