Guided-welded approach planning using a computer-aided designed prosthetic shell for immediately loaded complete-arch rehabilitations supported by conometric abutments.
In guided surgery, implants can be planned from radiographic guide information according to a restoratively driven treatment plan. Unfortunately, the palatal or lingual surface of teeth cannot be easily identified. The present article describes the use of a digitally designed prosthetic shell to improve the accuracy of guided-welded approach planning for immediate restorations supported by conometric abutments. Importing the virtual shell into the planning software provides an effective protocol for using the definitive prosthetic space information to plan the framework shape and position predictably. This method increases the accuracy of virtual planning and reduces the time needed to reline the prosthetic shell.
Minimally traumatic implantation and bone regeneration: a systematic review
Introduction: Dental implant procedures have reached about one million dental implants per year worldwide. In this context, it is necessary to establish the state of the art of minimally traumatic procedures for dental implants, especially after bone grafting procedures and/or use of biomaterials for bone elevation. Objective: Conducted a systematic review of the main considerations for optimizing techniques for dental implants by proposing minimally invasive procedures, especially after bone recovery or elevation processes through the use of biomaterials such as FRP and Bio-Oss®. Methods: The survey was conducted from June 2021 to July 2021 and developed based on Scopus, PubMed, Science Direct, Scielo and Google Scholar, following the rules of Systematic Review-PRISMA. Study quality was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: Studies have shown that guided preoperative planning and dental implant-guided jaw reconstruction provide high success rates for implant and dental rehabilitation. Furthermore, the concept of using personalized implants with the help of 3D virtual treatment planning can greatly improve mandibular restoration and help to achieve good facial profile, esthetics and dental rehabilitation, avoiding complications with grafts in general.
Haemopoietic activity and effect of crude fruit extract of phoenix dactylifera on peripheral blood parameters.
Aim: Phoenix dactylifera (date palm), has been reported to posses a variety of pharmacological activities which indicate its usefulness in various kinds of diseases and disorders. The present study was aimed at investigating the haemopoietic activity of crude fruit extract of Phoenix dactylifera (P. dactylifera) and its effect on peripheral blood parameters. 
Method: Fifty (50) Wistar rats weighing 100 to 200 grams and aged 2 to 3 months obtained from the Animal House of College of Medicine, University of Nigeria Enugu Campus were acclimatized for two weeks. They were divided into 10 groups of 5 rats per group labeled A1 ,A2, B1, B2, C1, C2, D1, D2, E1 and E2. The first 5 groups were orally administered with graded doses of the crude Aqueous Extract of P. Dactylifera (AEPD) (A1=0.4, B1=0.1, C1=0.52, D1=0.90 mg/kg body weight and E1 [control]= 0.24ml Dimethylsulphoxide (DMSO) while the second 5 groups were orally administered with graded doses of the crude Methanolic Extract of P. Dactylifera (MEPD) (A2=0.4, B2=0.1, C2=0.52, D2=0.90 mg/kg body weight and E2[control]=0.24ml DMSO). The administrations were once daily for 112 days. On Day 113, 2.5ml of blood samples were collected from each rat through the retro bulbar plexus of the median canthus of the eye into tri-potassium- Ethylenediamine tetracetic acid (K3-EDTA) anticoagulant container and bone marrow was also collected for the analysis using stantard operative procedure. 
Results: The results revealed dosage dependent significant increase in Absolute values, Red Blood Cell (RBC), Haemoglobin (Hb), Packed Cell Volume (PCV), Reticulocytes and Platelet count in both aqueous and methanolic extract when compared with the controls (p 0.05). 
Conclusion: The observed changes in this study has demonstrated that P. Dactylifera has haemopoietic effect when orally administered in Wistar rats.
