1. The socket shield technique involves retaining a portion of the root after extraction to preserve the buccal bone and soft tissue contours for an immediately placed implant.
2. Key factors for success include primary stability of the implant, presence of the buccal plate, and thin soft tissue biotype.
3. Advantages are optimal soft tissue esthetics, preservation of bone, and reduced treatment time. Indications are thin labial plates or fractured/decayed teeth.
4. The procedure involves sectioning the root and preparing a buccal shield for the implant to be placed immediately adjacent to. Studies show bone formation between the shield and implant over time.

The socket shield technique at molar sitesNaveed AnJum
The socket-shield technique for avoiding postextraction tissue alteration was first described in 2010. The technique was developed for hopeless teeth in anterior esthetic sites but has not yet been described for molar sites. Managing postextractive ridge changes in the posterior region by prevention or regeneration remains a challenge. The socket shield aims to offset these ridge changes wherever possible, preserving the patient’s residual tissues at immediate implants.

“One-Piece” Immediate-Load Post-Extraction Implant In Maxillary Central IncisorAbu-Hussein Muhamad
Abstract: This case report describes extraction of a fractured left maxillary central incisor tooth, followed by immediate placement of an one-piece implant in the prepared socket and temporization by a bonded restoration.
Materials And Methods: The tooth was extracted with minimal hard and soft tissue trauma and without flap reflection. The socket was prepared to the required depth and a Implant was inserted.
Results: The atraumatic operating technique and the immediate insertion of the one-piece Implant resulted in the preservation of the hard and soft tissues at the extraction site.
Conclusion: The “One-piece” dental implant and provisional restoration provided the patient with immediate esthetics, function, comfort and most importantly preservation of tissues. The one-piece implant design resulted in a high cumulative implant survival rate and beneficial marginal bone levels.
Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient’s expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal.
Surgical reconstruction is preferable but prosthetic approach may be necessary in some circumstances such as the presence of complex or large defects, requirement of the recurrence control, local or general contraindications of surgery, damaged neighboring tissues due to the radiotherapy, general poor health, failed reconstructive attempts previously made, refusal of the surgery by the patient, high esthetic demands, the desire for a quick recovery and palliatively operated patients.
Nowadays, craniofacial implants are used to support and retain such prostheses. Studies have shown successful retention and stability of auricular prostheses anchored to the temporal bone with titanium implants.
Immediate Implant Placement And Restoration With Natural Tooth In The Maxilla...Abu-Hussein Muhamad
Anterior tooth loss and restoration in the esthetic zone is a common challenge in dentistry today. The prominent visibility of the area can be especially distressing to the patient and requires a timely and esthetically pleasing solution. Immediate single-tooth implantation followed by immediate provisionalization is becoming an increasingly desirable treatment that offers numerous benefits over conventional delayed loading. Provisionalization for immediately-placed implants using the patient’s existing tooth can enhance the final aesthetic outcome if certain steps are
followed. If the natural tooth is intact and can be used as a provisional, the emergence profile can be very similar to the preoperative condition. This article outlines a technique to use the patient’s natural tooth after extraction to provisionalize an implant.

Periodontitis is a chronic inflammatory disease of the tooth-supporting structures. The treatment of this condition is based on the removal of local factors and restoration of the bony architecture. Traditionally osseous surgery has been performed by either manual or motor-driven instruments. However, both these methods have their own advantages and disadvantages. Recently, a novel surgical approach using piezoelectric device has been introduced. It is a promising, meticulous and soft tissue sparing system based on low frequency ultrasonic microvibrations. The absence of macrovibration makes the instrument more manageable and allows greater intraoperative control with an increase in the cutting safety in the more difficult anatomical cutting zone. This presentation emphasizes the mechanism of action, instrumentation, advantages and limitations as well as its applications in periodontology and implantology.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

7. Socket shield technique
• In 2010, Hürzeler et al. introduced a new method, the socket shield
technique, in which a partial root fragment was retained around an
immediately placed implant with the aim of avoiding tissue
alterations after tooth extraction

8. Principle of SST
• Preparation of root in such a way that buccal/facial section remains
in-situ with buccal plate intact
• Tooth root sections periodontal attachment apparatus remains vital and
undamaged to prevent the expected post extraction socket remodeling and
to support buccal/facial tissues – “ Biologic cheating”.
